The fitness concerns surrounding Bellingham date back to February, when he suffered a hamstring tear in his left leg during a domestic match against Rayo Vallecano. That injury saw him sidelined for a significant period, interrupting a season that has seen him become the focal point of Alvaro Arbeloa's tactical setup.
Although he recently made a return to action for Real Madrid, he did so in a limited capacity. He made a substitute appearance in the high-stakes Madrid derby win against Atletico, but it was evident that he was not yet operating at 100 percent. It is this lack of rhythm and the delicate nature of hamstring injuries that has prompted Tuchel to step in and prevent further strain.
