If there was one image to sum up the importance of Manchester United's dramatic late win against Watford this afternoon - it was of Ander Herrera.
The Spanish midfielder had been handed a start against the Hornets and looked good; laying on an assist for Memphis Depay's opener and generally pulling the strings for the Red Devils.
However things took a turn for the worse when the former Athletic Bilbao ace went down with a hamstring complaint mid-way through the first half and had to be replaced by Marcos Rojo.
Manchester United slowly lost control of the match in Herrera's absence in the second half, and eventually conceded an equaliser when Troy Deeney slotted him a spot-kick after a Rojo foul in the area late on.
With time running out it looked as though the Red Devils had squandered a golden chance to move to the top of the Premier League table, for a few hours at least - but then up popped Bastian Schweinsteiger to save the day, albeit with a bit of help from Deeney.
Schweinsteiger's attempt from out wide was deflected into his own net by the Watford man to seal all three points for the Red Devils in extra time.
And, despite his injury, Herrera could barely contain his delight, going crazy in the dugout behind Louis van Gaal and Ryan Giggs. On the pitch his team-mates were delighted too, with David de Gea - who had earlier pulled off a world class save to keep the scoreline at 1-0 - ran out of his goal and punched the air in relief as the ball hit the back of the net at the other end.
