Real Madrid need to find a buyer for Iker Casillas if they're to sign Manchester United goalkeeper David de Gea.

De Gea will only move to Real if Casillas leaves this summer. The United man is unwilling to compete with the Real captain for No1 status.

AS says there are five options under consideration for the Real keeper.

Tottenham, Arsenal, AS Roma, New York City FC and Fenerbahce are all monitoring developments.

For his part, Casillas has intimated he wants to stay in Madrid next season.
