Manchester City, who romped to Premier League success by 19 points last season, began the defence of their title with an impressive win away to an Arsenal side playing under new Spanish manager Unai Emery on Sunday.
Emery was reported to only have £50 million to play with prior to this summer's transfer window opening.
Favouring a 4-2-3-1 formation, Emery is likely to field new arrival Lucas Torreira at the base of his midfield with Granit Xhaka providing the necessary steel. "Then, the contract is for speaking with the club and the players".
The Gunners entertain Pep Guardiola's champions at the Emirates on Sunday.
"Defensively: first it is to be organised, recover the ball quickly".
"We do work on different formations in training".
Kanye West: I wasn't stumped by Kimmel's Trump question
Taking to Twitter to clarify the "stumped" moment, he wrote: 'On Jimmy Kimmel . we had a great time having a dialogue. You need a format where you can give a full-throated defence of your views, and again, nobody's arguing that point.
He'll be among the players Arsenal will have to keep a close eye on if they're to stand any chance of getting a result. I left it five minutes into the second half, after speaking to them and saying we needed to be on the front foot more. Remember your titles from a big career, but this is a new way to try to win more'. I'm gonna stick my neck out and say Cech, although Ozil and Ramsey are contenders.
"When we are thinking in an attacking moment, I want the goalkeeper thinking for that, he is the first". No way. I don't want to forget that.
"Or Manchester United. People ask how will they do, but I know a little bit about the manager and in that situation how good they handle that".
"Each player has this quality, this characteristic to help the team as a collective. We defended very well and were a very compact team".
Welbeck, 27, has traditionally played in more advanced positions during his career, but with Sead Kolasinac out for two months with a knee injury and Nacho Monreal also unavailable for their Premier League opener against Manchester City on Sunday, Emery has been toying with using the England worldwide as a left-back. Arsenal also signed veteran defenders Stephan Lichtsteiner - who is the Switzerland captain - and Sokratis Papastathopoulos, who are also seen as strong personalities both on and off the pitch.
Mahrez bent an effort just wide of the post as he looked to mark his Premier League debut for the champions with a goal with City taking nearly complete control of proceedings leading up to the interval.
