Having calmed down after the game and after rewatching the match. I feel sorry for our midfield. The setup, tactics were soo wrong. Bruno was no where near the midfield all game, it was basically 3 vs 2 all match in the middle. I agree that Casemiro made poor passes which led to chances, but even then we were too easy to play all game and in second half Liverpool basically took it easy but still had a Sobozli chance where he messed up in front of goal by taking too many touches and then Salah put it above the bar from 10 yards out.
Casemiro's mistakes has kind of given him a way out, but he needs to realize and change his suicidal tactics of allowing both FBs to go forward same time and leaving two CBs and Cas as three players with no one close by, playing midfielders so far away from each other with Bruno basically playing as a second striker.
He should be playing three midfielders all close to each other, giving them passing options, plus as Pep once said he prefers midfielders passing 5 yards instead of 15, because with 5 yards, even if you mess up a pass, the players can quickly swamp you and take the ball away, whereas for longer passes the recipient is taken out of the play completely. He does not have the tactical nous to understand this simple fact.
Lastly taking Amad out and Garnacho was also another blunder, which also made Mazouri toothless and Garnacho could not even control the ball and was bullied all game, let alone combine with FB.
I was ETH out last season, but sort of continued with backed him this season with new coaching team and new players, it appears to have no impact whatsoever. The slight silver lining is our team has improved overall and has good depth in defense and attack. Could do with another CM for replacement with Mainoo, except that we are in very good shape, so whoever we choose as a new manager will have a good squad to mould into his style of play and could get far better results.
