Louis Van Gaal said this week it could take £60million man Angel di Maria a year to adapt to life at Old Trafford - but it took the United boss 59 minutes to decide he had seen enough at St James ' Park . Another unconvincing display was brought prematurely to an end moments after Di Maria flopped a hopeless right-wing cross into a visitors ' box bereft of team-mates . But it could have been a different story if Di Maria - hauled off at half-time in Saturday 's 2-0 win over Sunderland - had made his mark inside the opening minute .

But all too often the fickers were extinguished by those lackadaisical losses of possession of inexplicable passes into empty space . And shortly after one wasted opportunity too many , Di Maria was substituted again with the home fans ' chants of 'what a waste of money ' ringing in his ears .
