Roberto Martinez has warned his Wigan side that Arsenal remain dangerous opponents ahead of Saturday's Premier League clash.
Arsenal's 5-2 victory at Reading on Monday alleviated some pressure but Gunners boss Arsene Wenger remains under scrutiny after a miserable run that has seen them fall well off the pace in the Premier League and dumped out of the Capital One Cup by Bradford.
"I don't understand it from the outside," Martinez said, when asked about his beleaguered counterpart.
"You look at this Arsenal side, they've had to cope with many players moving away and new players coming in. They need a little bit of time but I went to see them on Monday and they were very impressive.
"I thought the movement and the quality of play they had in possession was as good as I've seen from an Arsenal side. Players like Lukas Podolski and Santi Cazorla, they're starting to feel themselves in this league.
"This Arsenal side will never change the way they want to win football games, the football philosophy that they've got, and that's admirable.
"You're going to see this Arsenal side going from strength to strength. They're still in the Champions League, which is the best competition in the world, and I think this team has got a lot to offer."
Wigan triumphed 2-1 at the Emirates Stadium last season - their first victory at the home of Arsenal and a crucial three points in their successful fight against relegation.
"Our games against Arsenal are two teams with similar football concepts,"
said Martinez. "We both battle to have control of the football and the games are really open, there are chances. They're really exciting to watch, especially from a neutral's point of view.
"Last season going to the Emirates and being able to get our first ever win at Arsenal was a key moment in our season in terms of belief and assurance that we could achieve our aim and Saturday is going to be another incredible event - the last game in 2012 at the DW Stadium.
"It's been a fantastic year of football at Wigan Athletic and we hope we can give something to the fans to fit the occasion."
