It's pretty clear to me that Maz was supposed to jump into midfield in this scenario. It happened many times during the game. He's marking nobody and Spence(?) is unmarked in midfield. If he had done so we'd have been in a pretty solid 4231 shape.
I see the point in Maz jumping in and out of midfield to make a midfield 3.
But that is only if the wingbacks are creating so much that you can justify losing one man in the middle to offset playing two in midfield. And that also requires the 10s to be coming back and getting behind the ball. Zirkzee was playing more like a second striker from the 442 days yesterday and Garnacho a left winger.
The "wingbacks", to my eyes are not doing anything that a regular premier league full back wouldn't be doing. They are not playing with any kind of freedom, safe in the knowledge that they have 3 at the back to cover for them.
So that leaves Maz looking rather confused at times as he doesnt know when to step up or drop. As a defender, it must be counter intuitive for him to step into midfield to pick up a man when he can see his right back and opposition runners going the other way.....
I just think that when this system has not been fully figured out, while the players are not the right fit, when there is injury crisis and there is a massive lack of form, then it may be time to go back to basics.
For the last 20 games he has been driving the car while trying to change the tyres. Its not working so I feel it is time to do something where the players can just play and not be bogged down with too many tactical thoughts. We know they are not the smartest lot.
I thought it was great that he was sticking with his system at first because he could see who could and couldn't cut it, but i dont think anyone, including Amorim, thought it would be this bad. The PL is over, we wont get relegated (i dont think) but we need to find form in the hope of winning the Europa to back door into the CL. That would give him tens of millions more to spend.
And people say that if he changes now, then players will lose all respect. I think he loses more respect by losing more games.
With the injury crisis he has an excuse / reason to change to a different system to cover the midfield deficiencies.
Pick up 3421 again over the summer with an off season and hopefully some good acquisitions.
