Arsenal's top scorer, Thomas, has been ruled out for the next three matches after suffering an injury in training.

The striker was forced off during training on Monday and it is believed that he suffered a knee injury which will keep him out of action for at least three weeks.

Thomas had already missed one match this season with an ankle injury but his latest setback means he will be out of action until early March.

The news is likely to come as a blow to Arsenal, who have struggled to score goals this season and need all their key players fit and firing if they are to challenge for the title.

Thomas has been one of the standout performers for Arsenal this season, scoring 12 goals in just 14 league games. His absence could leave Arsenal short of firepower up front and make life difficult for manager Mikel Arteta.

However, there is still time for Thomas to recover from his injury and return to action. In the meantime, Arsenal will have to rely on other forwards such as Alexandre Lacazette and Eddie Nketiah to step up and fill the void left by Thomas' absence.

It remains to be seen how long Thomas will be out for and what impact this will have on Arsenal's chances of success this season. However, it is clear that Thomas' injury is a major concern for the team and they will need to find ways to cope without him for the foreseeable future.
