London-Sana
Chelsea beat Watford 2-1 in the Premier League on Saturday.
Abraham scored a goal and made another to lead his team to victory after receiving a superb pass from Jorginho hit the defense and then hit the ball over Foster in the fifth minute to join Leicester City striker Jimmy Varde and Manchester City striker Sergio Aguero as the top scorer with nine goals.
Foster recovered from the early goal and fought back with an early shot in the second half, but surrendered when Abraham crossed into Pulisic to shoot from close range, doubling the visitors' lead.
The win, their fifth consecutive league win, moved up to third with 23 points, eight behind leaders Liverpool and two behind Manchester City, while Watford, who have not won, remain five points from 11 games.
