Chelsea striker Tammy Abraham is undergoing extra shooting sessions.
The frontman, 21, has bagged four goals in his last two games - two against Norwich and then two against Sheffield United.
The Sun says Abraham is working hard behind the scenes to ensure he repays Frank Lampard's trust in him.
Abraham - who has enjoyed loan spells at Bristol City, Swansea and Aston Villa over recent seasons - knows he must make this season count, with Chelsea still behind a transfer ban.
That is why he, as well as Mason Mount, has stayed behind at Cobham to work with Lampard on his long-range shooting and hold-up play.
