#1 Press forward and attack

The frontline of United needs to attack relentlessly and be clinical in their finishing. Romelu Lukaku's poor performance against Baggies hurt United's chances; Paul Pogba was erratic throughout the game, and Alexis Sanchez had a match to forget against West Bromwich.
The introduction of Jesse Lingard at half-time added some bite to the frontline. His performance against Bournemouth was impressive, and Lingard will be crucial once again, as his pace, along with his ability to make runs will help United make inroads against Spurs.
Sanchez was rested, while Pogba showed glimpses of his talent against the 11th placed team.
Creating more chances leads to building up pressure, and when this happens, the opposition falters. They need to take a leaf out of Manchester City's book and play a similar game against Spurs.
It is the need of the hour for United to be creative up front and attack against The Lilywhites if they wish to proceed to the finals of the FA Cup.
