He is almost 26 and has played a grand total of 2 matches in european football. He was playing in Ligue 2 up till 2010. He screams mid-table player. I just dont think he will be a top four player.
To be fair that means nothing, some players can be picked from obscurity and turn out to be good players.
Look at Grant Holt, hes played in every main division in England, and some were even clamouring to take him to the world cup as Englands 4th striker.
Only this year will prove if he is good enough, but from what ive seen he does look the part IMO.
Wont score as many as RVP, but i think what he offers will help them share goals around the team.
