Wikipage has him down as a 6'1 central defender. He would be a good wingman on a 3 CB back line.
The Italian league where he plays FB? (your implication?) is not as quick as the Premiership. 6'1 is beyond the upper limit for what I think would be required for a great FB so I suspect he would not do so well in the Premier League at FB.
Since he is noted as a CB his most favoured position is probably CB, not FB.
I'm not claiming that CBs can't play RB/LB. Ivanovic and Huth, of all defenders, have played there.
I'm saying the best ones, on average, won't be built like CBs.
Play them FB, their relative lack of agility will be exploited all day by speedy, nippy wingers. This applies to the wingmen in a CB back 3 who have to cover the attacking WBs.
