Manchester City have significant concerns about the fitness of Phil Foden after their Champions League loss to RB Leipzig.

The Citizens did not suffer any consequences in the competition for the result, as they were already top of their group and through to the last 16.

However, Foden coming off at half time with an ankle issue was a very worrying sign for manager Pep Guardiola.

"Phil had problems in the beginning of the game with his ankle," Guardiola told reporters.

"He struggled a little bit so he was taken off as a precaution and we put Raheem (Sterling) in his position."
