Rashford nets winner for Manchester United

Elsewhere, Arsenal and champions Leicester City picked up their first Premier League wins of the season by beating Watford and Swansea City respectively while Tottenham Hotspur came from behind to draw 1-1 at home to Liverpool.

After a dismal title defence last season, Chelsea look revitalised under new manager Antonio Conte and the Italian was able to celebrate his third successive win after the most emphatic display of his brief reign. 

Eden Hazard put Chelsea ahead with a superb run and clinical finish from the edge of the penalty area in the ninth minute at Stamford Bridge. 

Willian was back for Chelsea after recovering from a calf injury and the Brazil winger doubled their lead in the 41st minute before Nigeria’s Victor Moses came off the bench to net the hosts’ third in the 89th minute. 

At Vicarage Road, Arsenal’s 3-1 win over Watford ended their winless run. Arsenal took the lead in the ninth minute when Santi Cazorla stroked home a penalty after Nordin Amrabat elbowed Alexis Sanchez. 

Chile forward Sanchez increased Arsenal’s advantage five minutes before half-time with a deft touch over Watford goalkeeper Heurelho Gomes. 

Mesut Ozil who was making his first start of the season headed goal in first-half stoppage time. 

Watford’s Roberto Pereyra reduced the deficit in the 57th minute, but the Hornets remain winless. 

Leicester City finally secured the first win with a 2-1 success against Swansea City. Jamie Vardy scored the first goal for the winners and Wes Morgan lashed in the second in the 52nd minute. Leroy Fer reduced the margin in the 80th-minute.
