Arsenal manager Mikel Arteta insists his side will have to be at their best against Manchester City on Wednesday, claiming his former side have “been very unlucky” recently.
Arteta became the permanent coach of Arsenal this season having previously worked under Pep Guardiola as his assistant at City.
And the 37-year-old says he has “a very clear idea” of what Manchester City will do and he thinks he knows how to create issues for them.
He said: “It’s going to be a very special night. I’m very excited to get back there.
“Now I’m in a different position on a different bench. I will defend my club as well as I can.”
The Spaniard was asked what has gone wrong at Manchester City, after Guardiola’s side were condemned to their seventh defeat of the season as they lost 2-0 to Man Utd in the derby on Sunday.
He added: “Sometimes small details make the difference. I think they’ve been very unlucky.
“This is football. It can happen.
“We have to be at our best that’s for sure to have any chance of winning the game.
“We are in two different processes and levels, we have to be at our best.”
