Pep Guardiola has refused to be drawn on Manchester City's attempts to sign Erling Haaland but said "many things are going to happen" when the transfer window opens this summer.

Sources have told ESPN that City are leading the race to sign Haaland, who has a €75 million release clause in his Borussia Dortmund contract, ahead of Real Madrid, Barcelona and Bayern Munich.

City are expecting to know more about Haaland's next move after the international break, although sources have told ESPN the release clause does not have to be activated before April 30. Guardiola was asked about the Norwegian striker at a news conference on Friday but remained tight-lipped about the club's transfer plans.

"Since I am here, every month or two months people say we are going to sign 50 players," Guardiola said. "Right now, listen, it's impossible that I am going to talk about some guy who is not here.

"He's a Dortmund player and we've an incredible run ahead of us. At the end of the season it is the transfer window and many things are going to happen.
