Why did no other clubs move for him? Jackson Martinez already looks a bargain for Atletico Madrid after finally leaving Porto for £21m.

Costing just £11m, Toby Alderweireld moves to Tottenham on the back of a superb season on loan at Southampton last term, when he was one of the best centre-backs in the Premier League.
