He would be a quality backup to Bellerin. He may even challenge for a starting spot. He appears to still have plenty of pace. The guy won 7 titles with Juventus - its useful to have guys like this around. He's a no-nonsense kind of player as well which I like.1 and 3 i can accept.
Lichtsteiner plz. He's basically a swiss james milner but with less crossing ability. A solid, physical player who does a job at RB. he's not quick, or technically that good but he is physical and solid and has lots of energy (although at 34, we'll see). Maybe that's what you boys need and tbh he's obviously just cover for bellerin.
