He is an ideal candidate for us right now.
1) If Mahrez goes - we need someone, pro player, who can cover both RW and LW positions...
2) He can score free-kicks like Mahrez and we will definitely need some of that
3) He learned his lesson I guess, there is no better place in world football, than City. Key is to be humble
listen to Pep and do your chores proffessionaly.
4) His skills and pace is something we lacked since Sterling left, not always these 360 turn arounds will work
5) In overall I have a feeling that from all the other players that have left, Sane still has some unfinished business left here, so why not...
6) If you look at the market, there are not so many players (I believe there is none but..), that fill all the above mentioned criteria.
