#3 Creativity
The Chilean can offer a lot more than goals. With his pace, technical ability, strength, dribbling skills and close control, he can create a lot of goal scoring opportunities for Lukaku and Co.
The Chilean provided 9 assists in his 2 seasons with Udinese. In three La Liga seasons with Barcelona, Sachez provided 27 assists, and for Arsenal, he has amassed a total of 25 assists so far.
His pace is an obvious strength, along with his trickery and ability to beat defenders. Jose Mourinho clearly lacks a creative player and Sanchez is one of the best at it. He will invariably increase the pace of the Manchester United attack and provide the cutting edge that United have been missing for quite some time.
Romelu Lukaku will definitely relish the opportunity to play alongside the Chilean and it will give him the opportunity to add a few more goals to his tally. With the catastrophic decline of Henrikh Mkhitaryan and the inconsistent form of Juan Mata, United desperately need a creator in the midfield.
