Arsenal boss Arsene Wenger has paid tribute to Champions League opponents Montpellier.

Arsenal may be Champions League veterans, now playing in the elite European competition for the 15th straight campaign, and Montpellier only just starting out having won the Ligue 1 title in May, but Wenger warned against any complacency tomorrow night when taking on a side who have lost three from the first five domestic games.

"What they did [last season] is a miracle because I think three years ago they were in the second division and one point away from relegation to division three," he said.

"It is difficult to know why they have not started well this season. Maybe because they were champions and now they are the team to beat.

"People have maybe a little less urgency and everybody is a bit more cautious against them."
