Real Madrid players, Jude Bellingham and Antonio Rudiger, had to be separated during a training ground bust-up, according to the UK Mirror.
This comes days before their UEFA Champions League quarter-final second leg against Arsenal.
Los Blancos were thrashed 3-0 in the first leg of the tie last week.
Real are hoping to pull off another famous comeback and book a spot in the semi-finals, where they could face either Aston Villa or Paris Saint-Germain.
Tensions are high within Carlo Ancelotti's squad as they prepare for the match, with reports claiming that Bellingham and fRudiger were at the centre of a training-ground clash.
The pair had to be pulled apart before Real travelled to face Deportivo Alaves in a crucial match for their LaLiga title hopes.
Bellingham is claimed to have been furious with a tackle by Rudiger during a small-sided game which had to be stopped in order to separate the pair.
