Erling Haaland ruled out of Manchester City's clash with Brighton

Haaland missed the FA Cup semi-final win over Chelsea on Saturday with a muscle issue and has now been ruled out of his side's trip to the Amex Stadium.

Guardiola insisted the matter was not a serious one for the 20-goal striker, who could come back into contention Sunday's clash with Nottingham Forest, and was boosted by Phil Foden and John Stones both getting the green light after their own fitness concerns.

"Erling is not ready for tomorrow, the other two - they are ready," he said.

"I know it is not a big issue, but he is not allowed for this game."

The defending champions are four points behind leaders Arsenal with two games in hand, with second-placed Liverpool taking part in the Merseyside derby on Wednesday night.
