Sorry for not wanting a player who couldn't score against the top 7 in the french league and when you take penalties out of the equation was a 1 in 2 striker in a poor league and made no impact in the Europa league. Yes, he's a GOOD player, not a GREAT player, Everton level at best imo.
In 2 years it'd be "why did Wenger sign another French player who wasn't good enough when we had Walcott, Welbeck and then Campbell and Wellington Silva out on loan"
Edit: oh and for the record, even if we wanted to sign he it would be tough, Lyon are in the CL, he is happy being the main man there and isn't going to want to swap that for being on the bench against one of his national teams rivals (a.k.a Giroud) having to adjust to a new role, new manager, new team and new league 12 months before his home Euro's after just starting to break into the national squad.
