@Beast. Shiiiit dude, it's not like we're about to finish the season and Kakuta hasn't played a minute all year, it's the first game for God sake. I would think that Carlo knows he has a great talent on his books and will look to bring him into the team slowly when he thinks he is ready and is doing extremely well in training. Give it time man.
Mikel is improving massively, 2 seasons ago I though he was absolute rubbish but he's really growing on me. He has great vision for a pass and does a good job winning the ball back for us and laying it off to more creative players. He makes a few clumsy mistakes but he'll learn and become a massive player for us in the future.
Ffs, this is really grinding my gears. People thinking they know better than Ancelotti. Leave him to it, he knows best, like others have said he's the guy that made Kaka and Pato.
