#2 The perfect service
While he will create opportunities for others, he will benefit from the creativeness that sits behind him in this Manchester United midfield.
With the likes of Juan Mata, Paul Pogba and Henrikh Mkhitaryan in close proximity, Lukaku will not be short of service from central positions this season, while players such as Antonio Valencia, Ashley Young and Jesse Lingard will be amongst those supplying the crosses that players with Lukaku's physical build thrive upon.
And as he becomes more effective, the more Lukaku will become central to everything that Manchester United do in attack.
Mourinho is still experimenting and fine-tuning his team to get the very best out of it, and while the tools currently at his disposal are some of the best in the trade, the second half of the season will see the return of Ibrahimovic, with the Swedish star desperate to make up for lost time.
If he can combine effectively with Lukaku, this could be Manchester United's year of what is now overdue glory.
