Real Madrid are weighing up a summer move for either Thibaut Courtois or David de Gea as they chase a new No 1 for next season. The European champions are desperate for an upgrade on current goalkeeper Keylor Navas and have their eyes set on the Premier League duo. And they want the Chelsea shot-stopper to stall on a new Stamford Bridge to give them thinking time, according to the Daily Telegraph. The Blues are hopeful the Belgian will sign an extension to his contract that runs out in 2019, but there has been little progress so far. Real plan on making a decision over their No 1 summer transfer target by April.
