Arsenal striker Olivier Giroud is looking forward to being reunited with his old Montpellier colleagues when they visit the Emirates in the Champions League this week.
Giroud, 26, has hit form after a sluggish start to life with the Gunners and bagged his seventh goal of the season in the 5-2 thumping of North London rivals Tottenham.
But the France international, who moved from Ligue 1 champions Montpellier to Arsenal for £13 million over the summer, has warned his new colleagues to be wary of his old ones.
He said: "I'll be happy to see them again. This year, things have not gone quite so well for them - they have had less success, but they are getting better.
"It's a must-win match for us, but Montpellier have nothing to lose now they are already eliminated. We have to be careful as that's when some teams are most dangerous.
"They didn't become champions of France with no talent. We must not take anything for granted."
Giroud told France's RTL radio station the Gunners had taken confidence from their thumping of their neighbours, for whom striker Emmanuel Adebayor was sent off.
He said: "This was a great performance in a derby. Lately, we have lost points stupidly, but this was good."
And he absolved France international team-mate Hugo Lloris, who was in goal for Spurs, of blame for the result, saying: "Hugo Lloris is a good friend. He could not do much about the goals, and he limited the damage."
