Mikel moves save chelsea career
You're referring to the incredible save made by Kepa Arrizabalaga, not Mikel, in the 2019 UEFA Europa League Final between Chelsea and Arsenal!
Kepa's save, which is often referred to as one of the greatest saves in Champions League/Europa League history, helped Chelsea win the penalty shootout and secure the title. The save was made in the 119th minute of the game, when Arsenal's Pierre-Emerick Aubameyang's penalty was heading towards the bottom left corner, but Kepa managed to get a hand to it and push it wide, forcing the shootout.
That save not only won Chelsea the title but also cemented Kepa's place in the club's history and earned him widespread recognition as one of the best goalkeepers in the world.
