Lichsteiner is a real leader, can't complain at that one at all. Fantastic signing.
I don't get anyone who's against that transfer.
1) Arsenal has been in need of a proper RB backup for ages
2) We have a young, promising RB in Bellerin, so no sense in splashing 15 to 20 on some french kid to rot on the bench (if you think you'd get them cheaper, look at the market and what Leipzig are about to pay for a virtually unknown)
3) Besides coaching and confidence, Bellerin seriously needs instant competition. Lichtsteiner will make sure he has.
4) The defence needs experience, and also Bellerin can only profit from an older guy who can certainly teach him one or two things
5) The guy has been a regular in a serial winning team, Juve
6) He's used to working with a tactically astute manager, Allegri
7) You could see in the CL that he's still top fit
8) He can cross the ball
9) He's free, so we're not reaching too deep into the transfer pot
