Real Madrid Transfers: 10 Players They Must Sign This Summer

10. David De Gea (Manchester United)

You have to feel for Keylor Navas. Almost every year, he keeps goal for the Champions League winners, and almost every year, he wakes up one summer morning to reports that his club are about to replace him with David de Gea.

The chances are that this trend is set to continue in 2018, even though Jose Mourinho has been quick to dismiss the idea that he could lose probably the only consistently world-class performer currently in his squad.

Look at it from de Gea's own point of view: he knows for a fact that the Galacticos are sweet on him, and in all probability he also knows for a fact that this United team, despite all the millions spent on it, is still a work in progress.

The career of a footballer being so short, there's only so long you can keep faith in a purported long-term project before you decide instead to bank on a sure-thing. Just ask Cesc Fabregas.
