Leno, 26, joined the Gunners from Bayer Leverkusen in June as new head coach Unai Emery continues to shape his own squad in north London.
The Germany international faces competition from Petr Cech and David Ospina to establish himself as first-choice goalkeeper heading into the upcoming season.
Cech, who ruled out a return to former club Chelsea despite the summer arrival of Leno, insisted last week he wants to fight for his place and offered some advice to his latest team-mate.
“You have to play your game and you have to find your way through,” Cech told the London Evening Standard.
“There are so many things that a goalkeeper coming to the Premier League has not experienced in a different league.”
Cech moved to Chelsea in 2004 and went on to win four league titles, the Champions League, Europa League and four FA Cups.
“Obviously you have the physicality and the way the game is played in the Premier League,” he added.
“The goalkeeper is not as protected as in Europe or different leagues. So I think that is something you need to find your way and deal with and obviously the quicker you do it, it is better for you.”
A former Arsenal number one, David Seaman, has also offered advice to the incoming Leno.
Seaman won nine major honours with the Gunners and gave the example of Manchester United’s David De Gea – who struggled on his arrival in England before developing into one of the world’s best goalkeepers – for Leno to follow.
“It is a totally different pace and physicality,” he said when asked to compare the Premier League to others in Europe.
“You look at David De Gea when he first came here he had big problems when he didn’t realise how physical it was in the Premier League but he adapted to that and really kicked on.
“With Leno, we have to wait and see what happens – if he is number one, we don’t even know who is going to be number one yet.”
The 27-year-old Algeria winger, signed from Leicester for £60million earlier this month, came off with an ankle injury in the first half of the 3-2 friendly win over Bayern Munich in Florida at the weekend.
After images subsequently emerged showing Mahrez wearing a protective boot on his left foot, his club said in a statement on Monday: “Riyad Mahrez has been given the all-clear to return to training later this week after picking up an ankle knock.
“A scan today has revealed no significant damage, and he could be available for selection for this weekend’s Community Shield against Chelsea.”
Pep Guardiola’s City face FA Cup winners Chelsea at Wembley on Sunday before opening their Premier League title defence by taking on Arsenal at the Emirates Stadium a week later.
The new Fantasy Premier League season is nearly upon us and managers are no doubt setting their teams – and then setting them again – in anticipation.
The key to a well-balanced FPL side is the shrewd recruitment of some budget players who could deliver great value.
To begin with, you’d ideally want one low-cost asset in each category.
Here’s a look at some of the players who fall into that bracket.
JORGINHO | CHELSEA | 5.0M
Jorginho comes with the guarantee of a regular starting berth of a top-six side, perhaps even one which will challenge for the title. The midfielder is absolutely crucial to Maurizio Sarri’s system and given his amount of passes per game – he managed 98.6 per game in Serie A last season, more than any other player – he is in the running for bonus points as well.
Fernandinho – who was priced at 5m last term – was relatively popular as he scored five goals and provided three assists for Manchester City. Jorginho could at the very least match the Brazilian having bagged two goals and four assists for Napoli last season.
LUKASZ FABIANSKI | WEST HAM | 4.5M
Swansea City had the worst defensive record last season and were unsurprisingly relegated as a result. Their goalkeeper Lukasz Fabianski, however, remained impressive between the sticks. He made more saves than any other keeper in the league and remarkably finished as the third-highest scoring in his position, just one point behind second-placed Ederson at City.
The Pole starred with three penalty saves to his name as well and has deservedly shot right back up to the Premier League with West Ham. Fabianski is a reliable option and best to be used in rotation with someone like Jordan Pickford (5m) or Matt Ryan (4.5m).
CEDRIC SOARES | SOUTHAMPTON | 4.5M
Cedric Soares was nowhere near the top defenders last season as Southampton consistently leaked the odd goal to surrender clean sheet points. That has seen his price drop by 0.5m this term. However, towards the end of the campaign, Mark Hughes changed their system to a back three with the Portguese deployed as a right-sided wingback.
With the freedom to get forward, he notched up three assists in the final seven fixtures. Many will have opted for Bournemouth’s Charlie Daniels for the same price but with the Cherries signing left-back Diego Rico (also 4.5m) this summer, the 31-year-old’s place is under threat.
MARKO ARNAUTOVIC | WEST HAM | 7.0M
Both Wilfried Zaha and Marko Arnautovic were midfielders playing as strikers last season. Both have had their categories changed this time around and both are showing fine goal-scoring form in pre-season. So how do you split the two?
The answer lies in the players around them. Arnautovic ran riot under David Moyes last season and now with Manuel Pellegrini at the helm and a host of creative players recruited, the Austrian should have plenty of service to feed off. The arrivals of Jack Wilshere, Felipe Anderson and Andriy Yarmolenko should make up for the absence of the injured Manuel Lanzini.
HELDER COSTA | WOLVES | 5.0M
‘Wait, don’t you mean Diogo Jota?’
Jota is on everyone’s radar having been listed as a midfielder despite frequently featuring as a forward and being Wolves’ top scorer in the Championship with 17 goals. However, he may not get as many opportunities to lead the line this season, or will at least have to earn them.
That’s because Wolves have signed Mexican striker Raul Jimenez on a season-long loan deal from Benfica, handing him the No9 shirt. Instead, pacey winger Helder Costa could prove just as productive as Jota on the other side of Jimenez and is available for a bargain 5m.
