Chelsea manager Frank Lampard has said that Callum Hudson-Odoi needs to learn more after the winger made his return from injury on Wednesday.
Hudson-Odoi started in the Carabao Cup against Grimsby Town, and scored his side's seventh goal of the game in the 89th minute as the Blues romped to a 7-1 win.
The winger played his first senior minutes for the Blues since suffering a ruptured Achilles tendon in April.

Hudson-Odoi nearly left Chelsea to join up with Bayern Munich last winter, but the academy product ultimately stayed at Stamford Bridge and last week signed a new five-year contract with the club that will see him earn up to £180,000 per week.
