Henrikh Mkhitaryan's thumping strike saw Manchester United overcome Tottenham and their Old Trafford struggles, but the in-form Armenian's serious-looking injury took the edge off Sunday's much-needed victory.
Promising displays have not brought with them anywhere near enough points this season, but United brought a frustrating run of four successive home Premier League draws to a timely halt.
Mkhitaryan marked another fine display with an excellent first-half strike against Tottenham, securing a 1-0 victory that the attacking midfielder was unable to celebrate properly after exiting on a stretcher.

"If I had any idea how to spell number 22's name I would commend him on an expert finish to give @ManUtd the lead." - Former England striker Gary Lineker.
Mkhitaryan. It seems almost inexplicable that the Armenian was left out of the United squad, never mind starting line-up, for so long this season. Mkhitaryan has grasped his opportunity to impress Jose Mourinho impressively, shining yet again as Spurs were overcome at Old Trafford. It was a shame to see the match-winner leave the pitch on a stretcher following a late challenge by Danny Rose.
MOMENT OF THE MATCH
Harry Kane's uncharacteristic sloppy pass was capitalised on with a cutting edge so often lacking in United's league campaign. Ander Herrera collected the ball and fed Mkhitaryan, who broke through and rifled home the winner.
STAT OF THE MATCH
United's victory ends a run of four successive Premier League draws at Old Trafford. Mourinho's side had won just one of eight league matches heading into Sunday's game.
