Don't doubt Tata and his pistachio shirt. The man is a serious coach, and a fantastic manager. Stress on the word manager, cus he gives me the vibe that he knows exactly what he is doing out there when it comes to resting players and keeping the team in order.
I don't see him having the motivational skills of Pep per say, or that innovated drive, but what he has is tremendous leadership, managerial experience, seriousness in intent and a great ability to keep everyone with their eye on the ball. Perhaps this exactly what the players needed. After the bathing of football knowledge and innovation they got from Pep here comes a guy, who's not going to stub the team's growth, will even add his own ideas, but is more down to earth and traditional and can give more stability in contrast to the dizzying era of football philosphy from Pep.
I like Tata. I think we made a fantastic choice in him.
