2 things. Win titles and begin to play pressing, aggressive defensive and immediate counterattacking football. We have most of the personnel to pull it off. Aggression will paper over some of our deficiencies and DDG will paper over the rest. I'd like for us to become the most tenacious, pressing side in the world. We can do it with the speed, strength and athleticism like this lineup:
DDG
Valencia-Bailly-Lindelof-Young (or Shaw if he continues to impress)
Pereria(or Herrera)
Lingard-Pogba-Fred-Rashford
Sanchez or Big Rom
With bench players like Shaw, Herrera, one of the strikers, Martial.... We can play very aggressive (win the ball back immediately) type soccer where we press, win and attack with purpose. This is the style of play I would like to see and I think another manager dropped into the squad could have us playing this way in no time. We do play this way at the beginning of most games and for spells. Mou doesn't force us to just keep the ball like LVG did and he doesn't discourage taking risks. But on the other hand, he doesn't demand that we press as a style which I believe lets many lesser teams stay in the game with us and with our quality all over the pitch, the faster, more pressing the game, the better I believe we would perform. When teams are allowed to slow the game and we pack our defense back into the final 1/3, I believe it negates our pace and quality. We need open spaces for our runners. We need press created turnovers to let our runners out of the gates. We have fast players all around the pitch and players that seem like they have a very high workrate. Those 2 things alone can be the foundations of a gameplan for a lesser squad. BUT when you add that our pace is packed into players like Big Rom, Rashford, Martial, Lingard, Pogba, Fred, and maybe still Shaw and Valencia who have greater quality than the average premier team, then I believe the more we can create a pressure cooker environment, the more we expose other team's deficiencies. That's always been my strategy when I coach kids, pressure and force mistakes by lesser skilled players or lesser athletes.
