#1 Find the best position for Paul Pogba
This is probably the biggest problem on Jose Mourinho's plate right now. How does he fit the club's most expensive signing in his team in order to bring the best out of him?
Sticking to a 4-2-3-1 formation at the start of the season, Mourinho played Pogba alongside Matic, saddling him with defensive duties. While he played well in patches, the Frenchman often looked confused on the pitch, not knowing whether to join the attack or stay back in midfield to defend.
After being urged by fans and pundits alike to play a 4-3-3 formation with Pogba featuring on the left of a midfield trio, Mourinho decided to give it a go. But the result was the same with Pogba and Mourinho even being seen arguing on the touchline against Tottenham in the league.
There is no doubt that Paul Pogba is one of the best box-to-box midfielders in the world. Once he has the freedom to attack, like at Juventus when he played with Vidal and Pirlo in midfield, he has the quality to rip open defences at will.
But unlike at Juventus, he has the responsibility to track back and defend at United, which doesn't get the best out of his primary qualities: skills, pace, strength, shot power and the killer final pass.
Mourinho has already made signing a central midfielder in the summer his priority, with one eye on the departures of Michael Carrick and Marouane Fellaini, and the other on how it would free Pogba up.
A Manchester United attack featuring Pogba in a free role, alongside Sanchez, Lukaku and Rashford would be quite a sight to watch.
