I am one of those who thought he would be a good buy. But that was pretty far off, don't know what it is but he looked very good for Frankfurt and had a lot to his game. He was also played for all of France's youth teams and managed 13 goals in 20 matches for the U-21. Don't know what happened, West ham, Moyes or just different teammates, but he looked a very solid player for Frankfurt and shit for West Ham.
But I was well off thinking he would be a good signing for this league. Worth half after 18 months is something that happens to luxury cars not players.
