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.
