Thomas Vermaelen believes Arsenal learnt some valuable lessons from their previous meeting with Montpellier, but will still need to be wary of the French champions on Wednesday.

Arsène Wenger's side kicked off Group B with a hard-fought 2-1 win in the south of France in September, but Vermaelen expects Montpellier to play with freedom at Emirates Stadium now they can no longer qualify for the knockout stages.

"We will need to be positive against Montpellier," said Vermaelen in his programme notes for Wednesday's match. "They will come here relaxed because they have nothing to lose.

"What I learnt from the game in France is that they have some very technical players who caused us some problems, especially in the second half. We have to be wary of that."

Vermaelen said that he has also been speaking to Montpellier old boy Olivier Giroud, among others, about what to expect from the visitors.

"We spoke to Olivier about them before the first match, because he could tell us a lot about his old team. I spoke to the other French players too, because they have seen them play a lot and they know their strengths and weaknesses.

"Anyway we have a few guys here who work well on analysing the opposition, and give us videos we can work from."

Arsenal go into the match in second place in Group B, knowing a win could seal qualification with a game to spare.
