Manchester City will demand a 20 per cent sell-on clause if Carlos Tevez is sold for a cut-price fee in January.

Officials fear top clubs will be put off by a £40million valuation and the Argentina striker's conduct in Munich, where it is alleged he refused to go on as a substitute, which he denies.

City are preparing to take a huge slice off the price tag in return for a cut of any future fee. (Argentina, Carlos Tevez, English Premier League, Manchester City)
