The Frenchman trained ahead of the fixture despite suffering a recent hamstring injury and reports claimed he would be involved in the clash which could hand Barcelona the La Liga title.
Mbappe has found the back of the net on 41 occasions in 41 appearances, following on from the 44 goals that he managed in 59 appearances during the 2024-25 campaign.
Despite this, his attitude and recent trips abroad while the season is still ongoing has led to many calling for him to leave the Spanish giants in the summer transfer window.
Now, as per The Athletic, fans will get their wish in some way as the striker has been ruled out of the Barcelona clash later this afternoon as he failed Sunday’s fitness test.
Barcelona have won 29, drawn one and lost four of their 34 league matches this season to collect 88 points as they forge a path towards another league title.
Meanwhile, Madrid will go trophyless this season which has led many to use Mbappe as a scapegoat for their poor performances.
Madrid are currently second in the La Liga table, 11 points behind of the leaders Barcelona, who need just a point on Sunday night to secure the title.
Head coach Alvaro Arbeloa insisted that he had no issues with Mbappe's recent trip which sparked fury that won’t be seen towards the striker this weekend as he continues to rest and recover.
