I don't know this dude at all, but he has started for Benfica and Atletico Madrid in the past two season, so I don't see where the Padoin comparisons make much sense.
As I had stated a few weeks ago, if this move facilitates Asamoah going back to the midfield once he is healthy, then it's ok by me.
Certainly not a sexy acquisition by any stretch of the imagination, but even if he does perform as solidly as Padoin did for the past two years, then I won't complain
