Erling Haaland and Phil Foden, two players for Manchester City, were not present during practice on Tuesday.
This has sparked concerns that they could miss their Premier League trip to Brighton on Thursday.
When they defeated Chelsea on Saturday in the FA Cup semi-final, Haaland was not even in the starting lineup.
The playmaker, who also happens to be City’s second-leading scorer, Foden, is now another concern after missing practice, according to the Independent.
If Pep Guardiola’s team defeats Chelsea and Everton, respectively, they may enter the match at the Amex Stadium four points behind championship contenders Arsenal and Liverpool.
