That's Lloyd Kelly, who we've been linked to. He's 6'3'' and plays both CB and LB.Of more value would be a player who could play left sided centre half and left full back. Gomez and Fabinho give that versatility and flexibility on the right side. Ox has played full back for Arsenal, Milner has played both fullback positions too.
Lovren, VVD and Matip are centre back options only I think.
