It allows us to go to 4 at the back if we want and be flexible. Evra swings to the leftback role and alves plays rightback and then Sandro plays as a left midfielder in a four midfield or even a diamond.
WE can adjust to what Lyon brings to the table and Lemina also provides us that defensive anchor in the middle.
I'd prefer Evra as a CB than as a full back. Less likely to venture forward and be caught out of position.
Of course, the best solution would be playing Benatia, but I guess Allegri wants a left footed CB in our lineup.
HD will this night not be high definition, but ultra HD.
Evra is cb isn't a bad idea. He is defensively really good and he is a little bit faster than our other cb's so he can take up if he makes a mistake. His only weakerpoint is he length (1,74m) for a cb, but again I think it is a good choice, Lacazette (1.75m) and Fekir (1.73m) aren't tall as well.
