Kulusevski, besides the lucky goal was tragic, lost every ball. Wouldnt give him more than 6.
Mckennie, Locatelli, Dybala and Morata were the best players for us, but imo looking at last minutes - Szczesny was MotM, even though i think he should have try to clear that cross from the corner which led to their first goal.
Worse players, as always Kean and Bentancur, personally i would rate Benta even lower than Kean. Rodrigo lost two crucial balls in the first half which probably should end in our net. Can only imagine how frustrating for Loca is to have him as partner, u could see he was doing everything (and not only thing, the whole defence) to alarm Benta that someone is chasing him from behind.
