Would be over the moon to have him as our chief scout.
I think he's very overrated to be honest. Since he started to get lots of recognition, the majority of the signings that would be perceived as at least being reasonably successful are:
Cabaye - a league and cup double winner with Lille
Cisse - Bundesliga top scorer
Tiote - league winner in Belgium and Holland
Santon - 40 games for Inter Milan, some of which came in the Champions League, along with 2 league winners medals
Ba - there for all to see in the Premier League with West Ham along with a little over 1 in 2 record in Germany
Sissoko - a French international who had interest across Europe for his performances in Ligue 1
I can't be arsed doing any more because it's easy to see where I'm going with this
Of the lesser know signings, there ones where it would be far more impressive if they ended up being successful, not many (if any) have been successful. Abeid, Haidara, etc.
They've signed a number of good players and of that there is no doubt, but I'm not sure how much scouting had to do with that. Their successful signings were all reasonably well known at the time and it wouldn't be beyond a football fan who watches a lot of leagues to have identified them as being good players, never mind a scout whose job it is to do so! I'm not sure why people seem to think he has done anything special.
