Chelsea manager Frank Lampard has cautioned highly-rated youngster Hudson-Odoi to add goals to his game if he wants to play as a winger at a top club.
The 19-year-old is yet to hit form after recovering from an Achilles injury he suffered in the 2-2 stalemate with Burnley in April last year.
"The one thing these players have over us from our era is that from the age of 10, they've been watching videos of themselves," the boss said, speaking of the difference in football epochs.
"They do studies: what are my weak points, my strong points? We had a whole video about wingers making the box going into Burnley last month. Then when Callum scores that tap-in, it's probably my favourite goal of the season.
"Look at Raheem Sterling, Sadio Mane, Salah and ask why they are racking up numbers. If you want to play as a winger at a top club, you have to get goals."
He has scored three goals and provided five assists for Chelsea in 23 games across all competitions so far this term.
