Angry Maurizio Sarri rounded on his over-confident Chelsea stars after their title hopes suffered another major blow with a 2-1 defeat at Wolves.
Raul Jimenez and Diogo Jota struck in four second half minutes to stun the visitors who now sit 10 points behind Premier League leaders Manchester City.
Ruben Loftus-Cheek’s deflected opener had put the visitors in control before they slipped to a second straight away defeat after gifting Wolves a way back.
Chelsea, who sit fourth, host leaders City on Saturday and Sarri was annoyed at their complacency.
“After this match we are less confident but maybe it’s better because sometimes my players show me that they have too much confidence,” said the boss, who made five changes.
“I am really very worried, not for the result but the fact that after the first goal we conceded we did not react very well. I am really very worried for this, not for the result.
“We played well for 55 minutes. After the goal for 1-1, which was an accident because we were in full control of the match, we were suddenly another team without the right distances and without our football.
“I don’t know why. I don’t think it depended on the changes, it depended on the mentality of the team.
“I saw a team without a reaction. You can lose a match but not without a reaction.”
Sarri also conceded City are out of sight with his side battling for a Champions League spot.
He added: “Manchester City are in another category. We have to play and fight for the top four. It is a very difficult result for the top four.”
Loftus-Cheek struck in the 18th minute when his effort hit Conor Coady and flew in.
Ryan Bennett’s goal-saving tackle denied Willian in the first half and Alvaro Morata missed an excellent chance immediately after the break.
Wolves then turned the game in four second half minutes. Jimenez drilled through Kepa Arrizabalaga after 59 minutes before Jota tapped in at the far post from Matt Doherty’s cross after Andreas Christensen and Willian gave the ball away.
It lifted Wolves up to 12th and was their first win for two months after five defeats in their previous six games.
Jose Mourinho praised the “big soul” of his Manchester United side in their 2-2 draw with Arsenal but bemoaned costly errors.
After a positive opening by United, David De Gea allowed Shkodran Mustafi’s header to slip through his hands, with Ander Herrera failing to clear in time on the line.
Arsenal’s second goal saw Marcos Rojo try desperately to make up for his error in giving the ball to Alexandre Lacazette only to slide in and score an own goal.
United responded quickly both times, with Anthony Martial grabbing the first equaliser before a calamity at the back for Arsenal allowed Jesse Lingard to nip in and level only 13 seconds after Rojo’s own goal.
Mourinho was forced into a number of changes by his ever-growing injury list, particularly in defence. He selected Chris Smalling and Eric Bailly despite neither being fully fit while Rojo made his first appearance of the season and Diogo Dalot his first ever start in the Premier League.
Mourinho said: “Maybe we feel frustrated with the result, we feel frustrated with some mistakes, we feel frustrated with some moments where a little bit more quality would be needed but we have to be happy with the spirit, we have to be happy with the effort, the dynamic, the intensity.
“The team had a big soul. We scored four goals and we drew 2-2. Even in matches like today where we play well, we always shoot ourselves.
“But good performances. I could speak about everyone. Especially in moments where we are not very happy with the result, we need happiness on the pitch.”
Mourinho dropped Paul Pogba and Romelu Lukaku to the bench, with both coming on in the second half, but denied the team’s level of happiness was improved by neither being in the starting line-up.
He said: “I think Paul came on and gave a good contribution. I brought freshness and power to the attacking players but our defenders were dead. That made it more difficult to keep that happiness for the 95 minutes.
“In the last part of the game it was Arsenal wanting the draw, diving, getting the game stopped.”
Mourinho reserved special praise for 19-year-old Dalot, who showed plenty of attacking intent down the right.
“The kid Diogo, fantastic,” added the United boss. “I think Gary Neville must be thinking now that Manchester United has a right-back for 10 years.”
Martial limped off during the second half but Mourinho offered a positive assessment, describing the Frenchman’s problem as a “pre-injury” after he felt tightness.
In a game crammed full of fouls, blunders and other feisty incidents, it was only fitting that another defensive error – the woeful Sead Kolasinac chief culprit – allowed Lingard to steal in for the equaliser.
Shkodran Mustafi’s header was ruled over the line via goal-line technology and an ultra-rare David De Gea blunder before Anthony Martial levelled things up despite a marginal offside shout on Ander Herrera.
Alexandre Lacazette very briefly gave the Gunners sight of the three points, this time Marcos Rojo losing possession in the build-up, but Lingard replied almost straight from kick-off.
Bernd Leno – Was barely an effort that needed saving. But could he have done better in parrying the Marcos Rojo free-kick – that resulted in Martial’s goal – out of danger? Probably. 6
Sokratis Papastathopoulos – Arsenal are becoming a hard-nosed side under Emery and Sokratis showed off his iron snout for the most part, but a mark has to be taken off for his weak challenge on Lukaku that led to the Lingard tap-in. 6
Shkodran Mustafi – Simply bullied Chris Smalling for the header that led to De Gea’s howler and is looking stronger alongside Sokratis with every passing week. 7
Rob Holding – Started the match confidently, helping weather United’s early pressure, before being stretchered off due to what looks like a nasty knee injury. 6
Hector Bellerin – Matteo Darmian was a clear weak spot in an altogether poor Red Devils defence, but Bellerin was surprisingly timid in the final third. 5
Lucas Torreira – The yapper and scrapper also looks pretty dapper with the ball at his feet, and put in another fine all-round display at Old Trafford. Delivered the cross for the opener. 8
Matteo Guendouzi – Looked pretty ragged with Ander Herrera snapping at his heels, but gained some measure of composure as the game wore on. 6
Sead Kolasinac – Should have done much better when given the freedom of Old Trafford down the left at one moment in the second half. Then stumbled over his own shoelaces to gift Lingard United’s second. 3
Aaron Ramsey – His jersey was never far away from the action and that was to be his downfall, as he tweaked his ankle going in for a lusty tackle in the first half. 6
Alex Iwobi – It’s hard to see Iwobi forming a big part of Emery’s plans going forward, particularly with young gun Reiss Nelson firing on loan at Hoffenheim. His night was littered with poor first touches. 4
Pierre Emerick-Aubameyang – After a limp opening hour he finally extracted himself from Eric Bailly’s pocket and let a couple efforts fly, only being thwarted by a De Gea intent on making up for his first-half error. 6
Stephan Lichtsteiner (36′) – Got his head in the way of a dangerous looking Herrera header in the first half and was generally steady. 6
Henrikh Mkhitaryan (45′) – Helped set up the move that led to Rojo’s own goal and then could have played the hero after making space in between United’s hapless defence, only to blaze over from point-blank range. 6
Alexandre Lacazette (63′) – Seems to make something happen every time he is brought onto the pitch, though it nearly cost him dearly after Rojo’s wild lunge left him on the floor. 7
