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.
Didn't Kepa go on loan to Real Madrid from Chelsea?
If Kepa is indeed a good goalkeeper, it looks like there will be a loan extension later or Kepa will be bought by Real Madrid, considering that his loan period is only one season.
I also understand that Kepa is a goalkeeper who is quite reliable plus he was also one of Chelsea's mainstay goalkeepers while joining there but it would be a shame if later Kepa had to leave when his contract with Real Madrid expired.
i think this is one of those typical difficulties when highly talented players go on a loan to a strong club like Real Madrid. When they play an amazing season and Kepa performs in a considerably strong way for the season, what are the chances that Chelsea would not want him back especially when Real Madrid even wins titles with him? If they let him go, then it will be very expensive, but at the same time they will have Courtois as well.
But it could be an interesting transfer for Real Madrid because Kepa is three years younger than Courtois. He is not quite a new generation, but three years is still worth considering when Real Madrid thinks about the future on the goalkeeper position. Courtois' injury isn't a light one, it is a severe condition and it takes time to see whether his knee will fully recover.
