Good performance from Sebastien Haller
Haller did not have the best of starts against United, as the striker struggled to hold the ball up.
However, the 26-year-old forward grew into the game, played well, created a good chance for Tomas Soucek and perhaps deservedly scored the winner.
The 26-year-old Ivory Coast international took four shots, played three key passes, had a pass accuracy of 68.6%, won 12 headers, took 54 touches, and made two dribbles.
So far this season, the striker has made three starts and five substitute appearances in the Premier League for David Moyes’s side, scoring two goals in the process.
