Raheem Sterling and Manchester City found the perfect hangover cure as they shook off their Wembley frustrations to beat Watford 4-0 and equal a Premier League record. A double from Sterling and second-half goals from Phil Foden and Aymeric Laporte made it a Vicarage Road rout as City threw darts at Watford's goal, just as they did when winning 8-0 against the same opponents in September. The outcome meant City matched a Premier League record for the most goals against a single opponent in the same season, equalling the 12 that Blackburn Rovers put past Nottingham Forest in 1995-96 and that Tottenham plundered against Wigan in the 2009-10 campaign. And three days after losing to Arsenal in the FA Cup semi-finals, it was a reminder that City's season is far from over, with manager Pep Guardiola no doubt telling his players he expects performances from them leading into next month's Champions League resumption. When these teams last met, City sped 5-0 ahead inside the first 20 minutes, giving newly reappointed Hornets boss Quique Sanchez Flores, in his second spell at the club, plenty to chew over. Flores was sacked in December, his successor Nigel Pearson was dismissed on Sunday, and it was former West Ham and Crystal Palace midfielder Hayden Mullins picking the team for this reunion with City as an interim head coach. Watford, three points clear of the relegation zone going into the final week of the season, must have approached the City game with modest ambitions, given they also lost 6-0 to Guardiola's team in last year's FA Cup final. Sterling made the breakthrough in the 31st minute, given far too much freedom in the Watford penalty area to smash high into the left corner beyond Ben Foster.
