Xabi Alonso's departure from Liverpool is being complicated by a sell-on fee, it has been revealed.

The Times says the situation is complicated by the terms of the deal that led to Alonso moving to Liverpool from Real Sociedad for £10.5 million in 2004, by which the Spanish club are entitled to a sell-on fee of €6 million (about £4.75 million) if the player is sold for €16 million or less.
