Spain manager to take over at Real Madrid after World Cup
Previously, French manager Zinidine Zidane shocked the footballing world by announcing his resignation from Real Madrid . The former goalkeeper made a sole league appearance for Madrid as a player and later turned out for rivals Barcelona.
And United supporters are concerned that new Madrid boss Lopetegui will use Spain's World Cup campaign as a chance to lure De Gea away from Old Trafford.
The Spanish giants broke the news in a Tweet on Tuesday.
He has agreed a three-year deal with the European champions and will officially take charge after the World Cup in Russian Federation.
The France legend subsequently took the decision to step down, and a replacement has now been found, though expectations are unlikely to be any lower.
Whatever did happen, the timing is unfortunate for La Roja as they aim for World Cup glory and also for Los Blancos in their building for the 2018-19 season, while question marks over the coach's suitability for such a top job also persist.
