Chelsea boss Frank Lampard is delighted with Tammy Abraham's progress this season.

Abraham scored twice in victory over West Ham in midweek.

He became Chelsea's second-youngest player to hit 20 Premier League goals, behind only Eden Hazard, with his brace in Monday's 3-0 victory over West Ham.

Abraham now boasts 20 goals in 47 Premier League appearances, with five strikes so far this term.

"I'm very pleased with his form, and Tammy offers a lot," said Lampard.

“We saw that the other night against West Ham and we've seen that this season whenever he's played.

“Tammy and Olivier Giroud have offered us a lot in their own way at different times.

“Now he just has to keep working and keep progressing.

“Last season was a great, real breakthrough season for him in terms of Premier League and being Chelsea's number nine, and there's more work he can do.

“I'm very happy with him."
