Atletico Madrid are monitoring developments with Spurs centre back Cristian Romero.
The Argentina international is understood to be interested in exploring a move away in the summer as he looks to play Champions League football.
The 26-year-old was critical of the club's hierarchy and recruitment policy in December, highlighting a lack of depth to their squad in comparison to the Premier League's elite, following a glut of injuries.
Having missed a number of games this season through injury and suspension himself, he has also praised his national side's medical staff in comments that have been construed as a subtle dig towards his rehab treatment at Spurs.
