Pochettino changing Spurs’ fortunes
Gimenez was forced from the field in the first half during Atletico’s 5-0 rout of Las Palmas in La Liga on Saturday.
The Uruguay international was injured in a challenge with Kevin-Prince Boateng in the 25th minute and replaced by Thomas Partey.
Atletico are now awaiting further tests on Gimenez’s left leg to determine the severity of the injury.
Diego Simeone’s men make the trip to the Santiago Bernabeu on Tuesday, determined for revenge following last season’s heartbreaking penalty shoot-out loss to their Madrid neighbours in the Champions League final.
