Andrey Arshavin belives Arsenal's recent performances prove they are capable of "landslide" victories - and he wants one against Wigan.
However, with just two points separating the top three sides, Arshavin knows Arsenal cannot afford any more below-par performances.
"Unfortunately, we couldn't beat Wigan at their stadium. The next game will be held at the Emirates," Arshavin said on his official website.
"The performance which Arsenal showed recently in the championship allows us to achieve the landslide victories, so I hope that the upcoming clash will be no exception.
"We need to catch up with the two Manchester teams."
Arshavin could find himself back on the bench on Saturday, having played 70 minutes against Leeds.
The Russian has been criticised in recent weeks for some disappointing displays, but showed a bit of decent form at Elland Road, and was unlucky not to score in the first half when denied by a fine save from Kasper Schmeichel.
Arshavin, though, accepts Arsenal's all-round displays must improve if they are to overturn a 1-0 deficit in their Carling Cup semi-final second leg against Ipswich next week and reach Wembley.
"As for the domestic cups, I think that we were lucky and keep on being lucky with the draw," he said after the win at Leeds secured a home fourth-round clash with Huddersfield.
"We already know our next opponent in the FA Cup. Actually, to be honest, I do not even know the league they play in.
"We still have one problem in the second cup. This is Ipswich, that we have to beat at the Emirates with a difference of two goals. If we do it, we will move forward."
Goalkeeper Lukasz Fabianski, meanwhile, will again be out with his shoulder problem, while Abou Diaby (calf) and Sebastien Squillaci (hamstring) continue their rehabilitation.
"Denilson has been hit on the hip and we will see how he responds," said Arsene Wenger.
"Chamakh looks good, so overall I don't think we have lost anybody at Leeds. They are small doubts."
Wenger added: "Diaby and Squillaci are not far away but they will not be completely ready for the weekend. They will be one week I think.
"Fabianski is still out unfortunately with his shoulder. It still gives him pain and we have to be patient about that."
