You buy a holding mid, you get a coach who'll coach the team to play a 4 3 3 with Pogba and Bruno ahead of that holding mid. You get a coach who'll demand our team do more off the ball. Demand our players get fitter. Having our team have a coherent pressing structure with clear triggers for when to press, who to press and when to get into shape. You don't settle for playing the mediocrity that is McT and Fred. That you just don't don't.
The transfer window is shut now so its pointless looking back at who we should have signed. We have to work with what we have.
The way I see it, Bruno is the most important player in the team, he starts. The front 3 (Rashford, Martial, Greenwood) have goals in them, each can get 20 goals a season, so they start. Therefore, to complement the attackers we need more defensive minded/workhorse type players behind them to provide a solid base and protect the defense, especially when VAR can give penalties at any second. Liverpool got close to 200 points in the last two seasons by relying on their front 3, and having a solid, reliable base behind them in midfield, nothing fancy, no show pony's, win the ball back ASAP and give it to the front 3 etc. Granted our front 3 are not at their level, but its the model to follow.
The club has spent an absolute fortunate trying to accommodate for Pogba, when ultimately the problem is Pogba himself. We're not winning the league anytime soon if we're relying on players so consistently inconsistent, and Pogba is certainly that.
