Danny Rose and Gedson Fernandes have been omitted from Tottenham's Europa League squad for the group stages this season.
Rose, 30, failed to secure a move away from the club before the closure of the transfer window on Monday.
He may have to look for a club in the Championship before the domestic deadline of October 16 or face not being able to play until the new year.
The England left-back spent the second half of last season on loan at Newcastle after clashing with Jose Mourinho over of a lack of game time.
Fernandes, who joined from Benfica on an 18-month loan deal in January, has also been left out.
New signings Gareth Bale, Carlos Vinicius, Sergio Reguilon, Pierre-Emile Hojbjerg, Matt Doherty and Hart have been named.
