Manchester City manager Pep Guardiola said he hopes midfielder Phil Foden can replace the outgoing David Silva.
Foden, 19, could start against Dinamo Zagreb on Wednesday (17:55 GMT) with City already qualified as Champions League Group C winners.
Silva, 33, is leaving City after 10 years at the end of this season.
On Foden stepping up, Guardiola said: “That is our wish. Of course, David is a legend with the amount of games and titles, but we believe he can do it.”
The Premier League champions secured top spot with a 1-1 draw at home to Shakhtar Donetsk in their penultimate fixture and on Wednesday travel to face a Dinamo Zagreb side still with hopes of qualification for the last 16.
Ukrainian side Shakhtar are in pole position to finish as runners-up, but Dinamo Zagreb and Atalanta remain in contention.
