The world-class right-back left his boyhood club, Liverpool, last summer upon the expiry of his contract, joining a Galacticos outfit that includes Vinicius Junior and Kylian Mbappe. ‌Contract release clauseWhen they signed the right-back, Madrid inserted a monster £840million release clause into Alexander-Arnold's contract, so if any club was interested in buying him, then they'd have to fork out a fair bit of cash. The release clause was inserted with the expectation that Alexander-Arnold would be in their team for years to come. Spanish football teams are required by law to include a release clause in every player's contract, so the £840m (€1b) clauses are standard for elite players in the country. ‌Manchester City linksA highly unlikely scenario based on both the huge release clause and affiliations to Liverpool, Alexander-Arnold is being linked with a stunning move to City.
