Manchester City and Watford played out one of the most thrilling ties of the FA Cup fourth round on Saturday as City dramatically came from behind to march on in the tournament. Watford raced into a 2-0 lead at half time thanks to goals from Fernando Forestieri and Troy Deeney and it looked as though City's 100% home record and quadruple dream would be over. But the Citizens fought back in the second period thanks to a Sergio Aguero-infused performance and a dreadful blunder from Hornets goalkeeper Jonathan Bond. Aguero's scored twice after the interval to level the contest before Aleksander Kolarov's speculative shot from way out somehow trickled through the grasp of Bond and in. And Aguero completed his hat-trick late on to put some gloss on the scoreline and send his side through to the fifth round of the FA Cup. But it was a thoroughly hard-fought contest and the final score hardly does justice to a Watford side who, for an hour, looked as though they would pull off a massive upset. The Championship club can take great pride from this performance - but what else did we learn as City sneaked through to the next round in this FA Cup thriller? Click "Next" to find out.
