Ruben Amorim said Manchester United must "grow up as a team" after extending their winless start to the season by throwing away a 1-0 lead to draw against Fulham at Craven Cottage.
Leny Yoro's deflected header gave United the lead on 58 minutes after Bruno Fernandes had missed a first-half penalty. But substitute Emile Smith Rowe equalised for Fulham fifteen minutes later.
After losing 1-0 at home to Arsenal in their opening game of the season last week, United have just one point from two games and next face a tricky Carabao Cup tie away to League Two Grimsby Town on Wednesday.
