Chelsea boss Frank Lampard admits he's seeking better focus from Tammy Abraham after this week's win at Crystal Palace.

Lampard discussed Abraham losing possession against Palace and conceding a late chance to the hosts as a prime example of this.

"Tammy gave the ball away and has to react better," said Lampard.

"Of course I speak with the players when these sort of things happen. It's part of the development but that can only go so far - some things in football are basic and they need to be better.

"It's a mistake which can happen to anybody. Reactions and work ethic are where I would really come down hard but I think generally with the players we don't have that issue. We do make mistakes, maybe sometimes with the youthfulness we have, and that's something that we work on and we'll get better at."
