Pep Guardiola took a sarcastic dig at VAR and implied Manchester City will struggle to retain the Premier League title if decisions continue to go against his team.
City were denied what looked to be a certain second-half penalty in their 3-1 win at Bournemouth when David Silva had his foot stood on by Jefferson Lerma.
A review of the incident took place but the outcome surprisingly backed the original decision of referee Andre Marriner.
City were last week left frustrated during a 2-2 draw with Tottenham when a last-gasp goal from Gabriel Jesus was disallowed by VAR due to a contentious handball against Aymeric Laporte.
Guardiola appeared exasperated with the use of the technology and, when asked if his side deserved a spot-kick, replied in an sardonic manner: “No, no, no. Penalty? No.
“It was clear hands last game, clear hands. A penalty today? No, please.
“The challenge this season will be amazing for us after winning back-to-back two titles, the challenge will be great.”
Questioned about the information he had received at VAR briefings, he responded: “Ask to the VAR people, please. Don’t ask to me.”
Sergio Aguero’s double and Raheem Sterling’s sixth goal of the season returned City to winning ways after Spurs had controversially ended their run of 15 successive league victories.
Captain Silva, who was left writhing on the turf by Lerma’s challenge with the game at 2-1, contributed two assists on his 400th appearance for the club, while Brazil striker Jesus was absent because of a hamstring problem.
Guardiola praised his team for battling through a physical encounter on the south coast to make it nine top-flight wins from as many games against the Cherries.
“We knew it, we felt it (the physicality), a nice three points and a big compliment to the players, a few things to improve, that’s good it’s happened when we are winning games,” he said.
“The quality of our players in front made the difference and we won the game.”
After Aguero’s opener and Sterling’s 11th goal in 10 appearances against Bournemouth, substitute Harry Wilson gave the hosts hope by making it 2-1 with a stunning 25-yard free-kick in first-half stoppage time.
The Cherries had numerous other chances, with Adam Smith and Callum Wilson among those thwarted by Ederson, before Aguero made the points safe.
City goalkeeper Ederson also escaped with only a yellow card early on after wiping out England forward Wilson wide on the Bournemouth left.
Bournemouth boss Eddie Howe felt his side caused City plenty of problems.
“We did have our chances and that’s the frustrating thing today,” he said.
“Compare this game to our previous encounters against Manchester City, I think that’s the most we’ve created by a long way. I thought we were a constant menace to them.
“The lads left everything on the pitch, which is all I can ask of them.
“We’re frustrated to lose, of course, but a lot of positives to take.”
Goalscorer Wilson, who followed up last week’s strike at Aston Villa in style, was only on the pitch after Charlie Daniels was carried off on a stretcher with a knee problem.
Wing-back Daniels has just returned from a long-term knee injury and Howe is concerned the player faces another lengthy spell on the sidelines.
“I know it’s potentially serious,” said Howe.
“To see a player go off on a stretcher like that in the amount of pain that he was you fear for the worst.
“Until we get a proper diagnosis, it’s difficult to give you definites but we’re concerned for him.”
The Gunners were beaten 3-1 by Liverpool on Saturday as they lost their 100 per cent record and the bubble burst on what had been an encouraging start to the season.
It does not get any easier with the visit of rivals Tottenham next weekend but Luiz is adamant they have shown enough potential to at least be in contention for the top four, having failed last season.
To do that, however, they need to find a steely resolve – a criticism regularly aimed at Arsenal over the years – to prevent episodes like the one at Anfield.
And Luiz himself will have to cut out the mistakes as his tug-back on Mohamed Salah presented the Egypt international with a penalty which crucially made it 2-0 and took the game away from the Gunners.
Lucas Torreira’s late consolation papered over some of the cracks, although £72million summer signing Nicolas Pepe, on his full debut, offered some hope from an attacking point of view.
“There is frustration always but I think you also have to be intelligent and mature to understand we did a lot of good things and we could have scored two or three goals before they did,” said Luiz.
“It is always difficult to play there. Not many teams will go there and get points. I think you have to be clever to take the positive things and think about the future.
“This club has the potential to shine like it has shone in the past. We have a lot of talent, we have players with a lot of quality.
“Football is about the end not the beginning and we are going to have to try to fight to the end.”
Luiz’s £8million arrival from Chelsea in the summer was supposed to help stiffen up a brittle defence.
While he still has some adjusting to do in his new surroundings he is confident they will continue to improve and has set himself ambitious targets.
“I came here with the ambition to fight for the Premier League title, I want to fight for other competitions also,” he added.
“It was like that at the other clubs I have been at but it was not always easy, there were difficult moments.
“I am going to try to do my best every single day and try to help everyone to believe in this because I think this club can believe a lot because it has a lot of potential.
“Every week you have to think to get points and then you arrive in March or April and then you are there and then small details make the difference. So we will do that.”
Having lost 5-1 last December, the Gunners were beaten 3-1 this time but were under pressure for the vast majority of the game and faced 25 shots.
It took Liverpool until just before half-time to make the breakthrough, Joel Matip heading in Trent Alexander-Arnold’s corner. Mohamed Salah’s double early in the second half threatened to make it another battering but Arsenal rallied and substitute Lucas Torreira scored a consolation.
Emery said: “It was not all we wanted to do in the match because we wanted to keep the ball more, but their pressing was very strong. The second half the key was the penalty. I think (it was) very soft, I think usually it is not enough.
“But we continued our way, we opened more and they gave us more space to keep the ball. In the transition they are very strong and they scored the third goal.
“It was the moment we needed to show something different – not frustration, not (heads) going down. I think we showed character, also the impact with Lucas Torreira, with (Alexandre) Lacazatte and Mhiki (Henrikh Mkhitarayan) was good.
“Some players today made one step ahead, like (Joe) Willock, I think also it was a good match for (Nicolas) Pepe and Matteo (Guendouzi). (Dani) Ceballos struggled more than last week but it is one experience more for him.
“We need to be optimistic. I think we reduced the distance with Liverpool. At the moment it’s not enough but I think we can be, in some issues, positive.”
Emery admitted full-back Nacho Monreal, who played the full game, could leave the club before the closure of the European transfer window having been heavily linked with a move to Real Sociedad.
“With Nacho, one possibility is open and we are going to speak about that,” said the Gunners boss.
On the continued absence from the squad of Mesut Ozil, he added: “Today they are here the players who we think they were the best physically and to play today.”
Liverpool are now the only Premier League side with a 100 per cent record this season and extended their winning run to 12 league matches.
Jurgen Klopp felt this performance represented a step up, saying: “I was really happy with a lot of parts of the game. I think everything we did well in the first four games we did tonight longer, more precise and better attuned.
“And I loved the desire, the passion, the power, the energy we put into this game that made us really uncomfortable to play against. We have a lot to improve but it was a big step tonight and I’m really happy.”
