The last two performances have been encouraging but let's not get carried away just yet because there are still questions that Sarri must "answer" if he's to succeed here long term:
(1) In some ways, it's easy for the players to feel motivated because one game was a cup final while the other was against Spurs AND it's easy to adapt when you have taken a 6-0 and 3-1 thrashings against City and Spurs (fair play to Sarri for adapting his tactics but it is something he should have done 1-2 months ago, not wait till the sack threat or after some very bad thrashings). Question now is whether Sarri can motivate the players and get his tactics right in the coming weeks because we will be facing the lesser sides, who have caused us problems this season. Will Sarri stick with what has worked in the last two games or will he go back to the nonsense we saw before that? Also, what will Sarri do if we fall behind in games? Will he tweak his tactics OR just make like-for-like subs and hope something happens?
(2) His management of youth players. Sarri has been somewhat fortunate that Loftus-Cheek has "given" him an out to not play him often with his back injury. But CHO? He has done well pretty much every time he starts this season and yet, he still doesn't get more minutes that he deserves. Sarri said he considers CHO to be on the same level as Willian/Pedro but we can clearly see where CHO stands in the pecking order. And let's not forget that it was only last week that he took a RB off a RB and didn't bring CHO on when being 2-0 down at home. Whether Sarri likes it or not, the youth players (there are a few more elsewhere) should be part of our future and he needs to be more receptive towards them and use them, especially with the transfer ban looming.
(3). Stop sending out mixed messages. Stop saying A and proceeding to do B. This is something Sarri has continuously done all season and the biggest example is he's always criticized the players for bad mentality after defeats this season but what has he done in the following games? Selected the same players who he criticized. It's time he starts picking players on merit. He made a point by benching Kepa against Spurs. Shouldn't he be doing the same with under-performing players? Otherwise, what's the point of him stamping his authority with incident like the Kepagate?
