Anderlecht boss Besnik Hasi insists they have nothing to fear going into their Champions League clash with Anderlecht.
The Gunners needed two late goals to overcome Anderlecht a fortnight ago.
"I think Arsenal underestimated us in the first game, probably," Hasi said.
"If you want to beat the top teams in the Champions League, you need to be at your top level and hope they are not at theirs.
"From our game two weeks ago, Arsenal get a mental boost after (what happened in the) the last three minutes.
"They have had a boost in confidence - you can see a few of their players are now playing much better.
"They want to win the game. If they win they can go through with nine points."
