Arsenal's Jack Wilshere has pointed to a shift in mentality this season that has seen the Gunners emerge as the chief challengers to league leaders Chelsea, in a fascinating interview with the club's website.
Wins away to Manchester City and emphatically at home against Liverpool have seen Arsenal bury disappointing results against each side in recent times, and seemed to indicate a new found resilience that has helped the club maintain an outstanding run of form in 2015.
With the Gunners currently on an eight-game winning run, Wilshere and co come up against Chelsea on Sunday knowing that nothing less than a win will do if they have any hopes of making up the ten points between the two teams.
However, the England midfielder has highlighted the different methods Arsenal have employed this season to ensure they will not be rolled over as they have been in the past, and it could mean that there is a tremendously exciting game on the cards at the Emirates this weekend.
“This year we’ve started to analyse the teams a little bit more,” Wilshere said. “We’re going there with a plan and as a team we know what we’re doing, which is important.
“This year we’ve looked a real unit going to tough places and a real team. We want to be difficult to beat when we haven’t got the ball because we know what we can do when we do have the ball, but when we don’t we want to be difficult to beat. We’re starting to do that.
"There’s this confidence or belief that we can do it and that’s something different this season.”
Wilshere has only just returned to fitness after another ankle problem, with the 23-year-old making the bench for the FA Cup win over Reading.
He may yet feature against Arsenal's West London rivals, but with Chelsea themselves unbeaten in the league since New Year's Day, something has to give between the Premier League's top two teams when they line up, and it promises to be an unmissable affair.
The Blues put in an excellent defensive performance against Manchester United last weekend to first and foremost avoid defeat, before nicking a 1-0 win. It is a strategy Jose Mourinho may again employ at the Emirates.
One thing is certain, you can be sure Arsene Wenger and his players will have done their analysis on Mourinho's side.
