The recent Madrid derby that ended in favour of Atletico Madrid was full of controversies and questionable calls from referees, most of which did not favour Real Madrid.

One of the instances saw Kang-in Lee make a poorly-timed challenge on Real Madrid midfielder Federico Valverde while he was carrying the ball through midfield.

The challenge was made just before half-time and Real Madrid argued that it deserved a red card.

It was reported after the game that the midfielder has sprained his ankle following the challenge from Lee and could miss several weeks.

A recent report from COPE has offered an update on Valverde’s fitness, adding that inflammation continues for the player in his ankle.

Should the inflammation subside, the midfielder could undergo more tests tomorrow as Real Madrid still figure out the extent of the injury.

More tests could give Real Madrid a better picture of how serious Valverde’s injury really is, with current reports claiming anywhere between two to three weeks.
