Mourinho confirmed in his press conference that it was a 433 against Newcastle (well, his intention anyway), with Pogba and Lingard in front of Matic, which is what I was alluding to.
Now, he definitely needs to look at the balance and positioning, because it just seemed like Pogba and Lingard had no clear instructions.
From looking at the average positions that I put in my previous post, the both (Pogba and Lingard) are very narrow, when actually, in a 433, it should be clear who is on the left and who is on the right.
For example, below are two teams that play a 433:
Man City
Clear to see De Bruyne (17) is on the right and Silva (21) is on the left.
Napoli
Clear to see Allan (5) is on the right and Hamsik (17) is on the left.
vs Newcastle
Clear to see we have a front three and Matic holding, but not clear to see who is on the right and left out of Pogba (6) and Lingard (14). It's just a straight line.
Actually, the only time I can remember Pogba being played in the position he played for Juventus was against Everton, which funnily enough, was probably his best game this season.
Vs Everton
In this graphic above, it is now clear to see who was on the left and who was on the right.
Now, I do think Pogba and Lingard would benefit from having a strong, dynamic box to box next to them, i.e. Khedira, Vidal, Nainggolan, etc. It would provide a better balance. However, the both could play above Matic. Mourinho would need to work on their positions, though.
