The English defender has fallen down the pecking order under new manager Ange Postecoglou, having not made a single appearance this season.
The Australian manager clearly doesn’t see Dier in his plans, with Micky van de Ven, Cristian Romero and Ben Davies favoured ahead of him.
Dier is keen on reviving his career, so he has opened the door for a move away from the club.
It looks increasingly likely that Dier will not continue with Spurs beyond next summer when his contract runs out.
Portuguese club Sporting CP have expressed interest in the 29-year-old, while Roma are also trying to provide him with an escape route.
The Giallorossi have been hit with numerous injuries this season, with the absence of Diego Llorente and Chris Smalling over the past few weeks leaving their defence thin.
Jose Mourinho will bid to tackle the problems in the winter transfer window and has his sights set on Dier, who he previously worked with at Spurs.
If they fail to secure his services in January, the Italian capital giants are considering signing him on a free transfer next summer.
Mourinho has previously persuaded Paulo Dybala and Romelu Lukaku to move to the Stadio Olimpico, and he could perform a similar trick with Dier.
Roma have endured a less-than-ideal start this season, sitting tenth in the Serie A table after picking up only three wins in eight games.
