Callum Hudson-Odoi felt let down being snubbed by Chelsea boss Maurizio Sarri for Sunday's defeat at Manchester City.
It is the second away match in a row that the England youth international has travelled with his team-mates without even making the bench after he was overlooked against Bournemouth.
The Times says Hudson-Odoi has questioned why he was brought along with the squad to Manchester if he wasn't going to be involved.
The U-17 World Cup winner is a £45million target for Bayern Munich, who are looking to snare him in the summer after failing to nab their No 1 target in January.
The German giants are prepared to offer him £85,000-a-week in Bavaria, with the club's sporting director Hasan Salihamidzic reportedly falling in love with him.
Hudson-Odoi has featured in just four Premier League games this season, with his playing time totalling a mere 74 minutes.
