4-4-1 The obvious solution to going a man down when a goal up.
Specifically with us vs Young Boys after half time we could have had something like....
Lindelof Varane Maguire Shaw
Bruno Fred VDB Pogba
Ronaldo
And then moved Pogba up front whenever Ronaldo came off, and put Greenwood on the wing to keep up some threat. If anyone can keep hold of the ball with his back to goal and help move the team up the pitch, its obviously Pogba.
But we ended up with this tragic mess of a system
Dalot Lindelof Varane Maguire Shaw
Fred Matic Pogba
Lingard
