Erling Haaland has included a £128million release clause in his Manchester City contract which can be activated in two years' time, according to reports in Germany.
City confirmed the £51million signing of Haaland from Borussia Dortmund earlier this week, beating a host of European rivals to his signature ahead of the summer transfer window.
After scoring 85 goals in 88 appearances for Dortmund, the 21-year-old striker had become one of the most sought-after players in world football, but City were quickest to pounce on the cut-price release clause which recently entered his contract.
