Chelsea could recall Ethan Ampadu from his RB Leipzig loan.
Ampadu has not managed any playing time this season.
The Wales midfielder played an hour of the Dragons' 1-1 draw in Slovakia on Thursday night and impressed alongside Joe Allen.
And both Ryan Giggs and Frank Lampard are concerned over his lack of game time, according to the Express.
The former Exeter starlet, 19, is seen as one of Chelsea's most promising youth prospects and even Maurizio Sarri was happy to give him minutes last season, despite his infamous lack of rotation.
Julian Nagelsmann, 32, is Ampadu's boss at the Red Bull Arena, but has overlooked the deep-lying midfielder so far.
