Chelsea attacker Christian Pulisic described Kepa Arrizabalaga as "unbelievable" after victory at Watford.

It needed an outstanding save from Kepa from his opposite number Ben Foster right at the end to preserve the three points.

"He [Kepa] is unbelievable and he was there when we needed him most so we are all happy," said Pulisic.

"It was closer than it needed to be. We were unfortunate with the penalty, we were really dominating the second half but Watford put up a good fight at the end.

"That is where we want to be," he said of Chelsea's position near the top of the table. "We are a big club and we need to fight to be as close to the top as we can."
