Kepa is undoubtedly a good goalkeeper. Real Madrid have done well by adding Kepa to the squad. Kepa is expected to do better for the team than Real Madrid's previous goalkeeper.
Real Madrid affected by injuries and on their important players this summer, one thing I trust about the team, they don't depend on a single player, they played collective football. Real Madrid didn’t sign a permanent goalkeeper, because they have their primary choice which is Thibaut Courtois. The problem they currently face is, Courtois is critically injured and won't be available for games for months. Arrizabalaga Kepa was loaned to Real Madrid as a potential temporary replacement for the Thibaut Courtois, perhaps Los Blancos can turned the deal around and make him permanent signing, it all depends on the form and good records keep by Kepa.
Real Madrid are really lucky to get Kepa Arrizabalaga even though he is on loan. Since Courtois has been suffering from a long injury, it is clear that management is very worried. Previously, Madrid was also linked with De Gea but did not get the blessing of Ancelotti. Don Carlo really understands the needs of his team at this time and Arrizabalaga is a figure he really wants, if he is able to show his capacity then it is not impossible that he will be permanent from Chelsea because Kepa is also not included in Pochettino's plans at Chelsea.
