9. Signed a legendary player, also improved in all areas aside from the inevitable Buffon move. Loses a mark for sentimental reasons. We probably don't need an expensive CM signing if we play as I suspect we will (largely with 2 or 3 with Berna).
I could see rating it anywhere from 8 to 10 dependent on how you rate Emre Can (Bentancur too) and Mattia Caldara. If you rate Can highly, and think Bentancur is going to have a big season, than it could be given 10/10. If you think Can isn't the top class CM we need, and think Caldara is the next Nesta, an 8/10 is probably appropriate.
I'd give it 8.5 or 9. I'm not sold on Can as top CM and think Bentancur is really inexperienced and rather rash on the pitch... and though I doubt Caldara is the second coming (and Bonucci in juve form is obviously still much better), he's still a top young CB it would have been nice to keep for the future.
Second best mercato as far as team improvement goes for me, behind 2011 when he brought in Pirlo, Vidal, Lichsteiner, Vucinic. This team was obviously much harder to improve though.
The best mercato we have had in a very long time we have signed the best player in the world the prodigal son has returned which will help us against high pressing teams and finally we have kept all our key players.The only negative is marchisio leaving which leaves us with five midfielders but still we had a great mercato hopefully this team will win us champions league.
