The Blues were 2-1 winners against Watford at Vicarage Road on Saturday evening thanks to goals from Tammy Abraham and Christian Pulisic.
"I'm happy with how the players are playing". I thought they were outstanding'.
Speaking after their 2-1 defeat at home to Chelsea, Hornets boss Quique Sánchez Flores did not reveal the extent of Cathcart's injury, but told the Watford website that the centre-half did not have any problems with his back before the game.
Lampard joked that Abraham, whose goal was his 10th of the season, had endured a barren spell, having not scored in the previous three games.
That's a huge goal for Pulisic, especially after a rough start to the season.
Only Foster stopped Chelsea's dominant display yielding more goals.
The Blues took an early lead against their bottom-of-the-table hosts when Abraham reached Jorginho's pass and guided the ball over Ben Foster. The objective is to stay as long as possible at Watford and in the Premier League.
Chelsea had lost just one of their last 58 league games when leading at half-time, at Wolves in December 2018. A week after scoring a hat trick at Burnley, the American star scored again as the Blues went to last-place Watford.
Abraham was the provider with a low cross and Pulisic evaded Watford's dozing defence to tap in from close range.
That changed against Frank Lampard's men, but the Belgian has shown he can provide much needed help at the back for Quique Sánchez Flores, and that's why the Premier League side are looking to keep him around. However, in the 78th minute, Jorginho made a foul on Gerard Deulofeu, which was detected by VAR. The Spanish winger stepped up himself slotted home the spot-kick to reduce the deficit.
There was almost a dramatic conclusion to proceedings when the brilliant Foster, up in Chelsea's box for a free-kick, headed towards goal but Kepa Arrizabalaga denied him in the final act as the visitors held on.
