Chelsea made the trip to Watford for their Premier League matchday 14 fixture on Wednesday night. With only one point separating the league leaders from second-placed Manchester City, the Blues needed a win to maintain their narrow advantage at the summit. Thanks to goals from Mason Mount and Hakim Ziyech, Chelsea secured a 2-1 win, returning from Vicarage Road with maximum points.Watford, who only had four wins prior to Chelsea’s trip, needed a positive result to steer clear of the relegation threat. They started the game full of intensity and kept Thomas Tuchel's side on their toes.After 13 minutes of play, a medical emergency involving a fan forced the two sides to abandon the match and head into the tunnel. Following a lengthy stoppage, the two teams returned to the field and picked up where they left off.Watford dominated proceedings just like before, but it was Chelsea who scored through Mount against the run of play. Emmanuel Dennis helped Watford come back with a reply in the second half, but Ziyech’s late effort kept the hosts from securing a point.Chelsea needed to fight tooth and nail against a spirited Watford side to get all three points, but in the end it was well deserved.
