If you think Sari is the only problem or the biggest problem we have then you are just choosing to be ignorant. Sarri didn't sell Pogba, Vidal, Marchisio. Sarri didn't buy Khedira, Ramsay, Matuidi, Ramsay, Danilo. Sarri didn't extend Matuidi and Khedira for another year. Sarri didn't sell Spinazolla and give away Pellegrini.
Blaming Sarri is just choosing to ignore all the other gaps we have in this squad. You think Pep or Zizou could do much better with the current fullbacks and midfield?
