Benatia is better than that german $#@!
Well, to be fair, he`s been really unlucky last two seasons with his constant injuries, this campaign only he was unavailable due to an injury for 181 days and missing 14 official games for Bayern - (Transfermarkt). That is a lot, not Howedes a lot, but still. Before that, he was a beast, a very, very solid motherfcker.
IF, a big IF, he can put all those injuries behind him and return to his usual best, he would be a massive player, with 3-4-5 good years in front of him. Plenty of experience is another important thing here, a World cup winner, a Champions league winner, has 6 Bundesliga titles, won FA Cup in England and several German cups...
With our medical staff though, returning to his best seems like an impossible task and it is more likely that if he comes to Juve, he would participate in less or around 10 games per season, which is not worth the 30 mil euros.
