Real Madrid reportedly sold Sergio Reguilon to Tottenham this summer because of a disagreement between the full-back and Luca Zidane, the son of manager Zinedine Zidane.
Reguilon completed a £30million move to north London earlier this year, providing Jose Mourinho with another option at left back.
It appeared to be something of a coup, given Reguilon had just played an important role in helping Sevilla to the Europa League final, which they won against Inter Milan, during a loan spell.
But it was clear he had no future at the Bernabeu and within weeks of returning to the Spanish capital he had sealed a move to Spurs.
