"I’ve know him well for a long time because he played in Lille, Saint Etienne, in Marseille - a very difficult club to play for because you’re under extra special pressure.
"He can always deliver a special pass. He’s a highly gifted player and will add something - on the creative front - to the West Ham team, that is for sure," Wenger told Arsenal TV.
Wenger will be hoping his defence are wise to any attempted ‘special’ passes on Sunday, as he looks for a strong start to a Premier League campaign many believe could be Arsenal’s best in years.
It's been a very long time indeed since the Gunners were serious title contenders but the pieces now seem to be in place for a sustained challenge and questions will be asked should it fail to materialise this season.
Meanwhile, West Ham are free to focus on domestic duties after being dumped out of the Europa League on Thursday and, given the lack of depth in their squad, it could well prove to be a saving grace.
While European football would have been a fitting way to say goodbye to the Boleyn, pragmatism must prevail and the Hammers simply do not have the squad to compete on both fronts.
