Bellingham suffered minor muscle discomfort during the Real Madrid match on Sunday, according to reports from the BBC and other sources.
The England international was involved in several key moments for his team as they looked to secure a win against their rivals, but he did not seem to be at full fitness throughout the game.
It is unclear exactly what caused Bellingham's discomfort, but it appears that he may have been struggling with a minor injury or strain. The midfielder has had a difficult season so far, having struggled to make an impact for his new club after joining from Liverpool.
Despite this setback, Bellingham remains a key player for England and will be hoping to recover quickly and return to full fitness for the upcoming international fixtures. He will need to be at his best if England are to compete in Euro 2021, which could provide an opportunity for him to showcase his talents on a bigger stage.
