Unai Emery's side are fourth in the table, but will move to within one point of Liverpool with three points.
"I want to quickly [reach] our best performance, but I know we need a process", Emery said when asked if he will also need three years to return Arsenal to Europe's elite. If they play on Friday and we play on Sunday then for two days you think about the pressure being more on us.

"I don't think it comes as a surprise but I believe they'll find our team very hard work on Saturday. The characteristic each player has is important, and Iwobi can impact on the match", Emery said. I want to do it while enjoying every day.
