Bayern Munich target Callum Hudson-Odoi produced two assists to help Chelsea beat Nottingham Forest in the FA Cup third round.
This was only his seventh appearance of the season, and he has yet to start a Premier League game in 2018-19.
With Olivier Giroud, Pedro and Willian missing through injury and Hazard starting on the bench, Hudson-Odoi got another chance to impress - and he took it.
Playing on the right wing, his excellent deliveries made both goals for Morata, who scored his first goals in six matches.
Chelsea have reportedly rejected a £20m offer from Bayern for Hudson-Odoi.
