Input: Real Madrid will make a £25million bid for David de Gea this week and expect to have him at the club for the start of the season, meaning Manchester United will have to re-ignite their interest in Ajax goalkeeper Jasper Cillessen. With De Gea sitting in the stands alongside Victor Valdes and Anders Lindegaard during United's opening game of the season and the Spanish club convinced that Van Gaal wants to sell the player, the only obstacle remains the tough negotiating stance of United's executive director Ed Woodward.
