Wigan manager Roberto Martinez believes Arsenal are "reaching their peak" as he prepares to take his side to the Emirates Stadium.
The Spaniard was in the crowd at Elland Road on Wednesday to see the quadruple-chasing Gunners knock Leeds out of the FA Cup, and he feels he has seen signs that Arsene Wenger`s men are preparing to hit top form.
Wigan have lost just one of their last seven league games but go into the match in the relegation zone, and Martinez knows the hurdle that faces him this weekend is one of the biggest in the competition.
He told Latics Player: "They are very young players but technically very gifted, they know how to play, the manner that they always play, and whoever plays, you`ve got fresh legs and fresh ideas.
"They have a clear identity and philosophy to win football games, which makes them very, very attractive to watch.
"We`ve played them three times in seven weeks and you feel like they`re growing and getting better, stronger and reaching their peak."
