He's a shadow of the Mandzukic we could appreciate in the last three seasons in Germany and Spain. Slow on the ball, often unable to hold it, and poor/slow decision making. Since he returned from the injury he played like a thinner version of Llorente, and even before he was not really that sharp except the Supercoppa match. Since the match vs Udinese where he wasted tons of good chances it was possible to see that he was gonna struggle a bit to find himself in this new situation. Actually he cannot be a starter, honestly, but when and if he comes back, he's a player you have to start because he's one of the few real pure goalscorers left in the game, Trezeguet style. Of course he's not at his level.
