Gunners boss looking for first trophy since 2005
The Gunners needed a last minute penalty from captain Cesc Fabregas to keep them in the FA Cup on Saturday as they drew 1-1 with Leeds United at the Emirates.
Wenger has indicated that Ipswich, who appointed Paul Jewell as their new manager earlier this week, will also have “nothing to lose” as he looks to maintain Arsenal’s push for their first trophy since 2005.
The Premier League side are clear favourites to beat Ipswich but Wenger has warned his team about complacency ahead of the tie at Portman Road.
"We have been warned," Wenger said. "We will certainly be on our toes going to Ipswich.
"Our last game has shown that against a Championship team we must be completely up for it and focused from the first minute on if we don't want to be surprised.
"In the Premier League there are one or two players standing out where the club has spent a lot of money. In the Championship you face the team as a compact unit who is ready to fight against you, and I think that is what we will face against Ipswich.
"The pressure is on Arsenal and they have nothing to lose. That is part of being at Arsenal to deal with that and I accept that completely."
The Frenchman is expected to rotate his squad for the game against the Tractor Boys, with Laurent Koscielny, Jack Wilshere and Robin van Persie likely to return to the starting line-up.
"Maybe we were a bit unbalanced offensively in our team and maybe we have to be a bit more cautious in the structure of our team," Wenger said.
"I see the Carling Cup as a possibility of a trophy and that's how we will approach the semi-final.
"What is in the players' brain is a desire to win. Trophies are the consequence of your performance and the quality of your display."
