LONDON — Watching goalkeeper Kepa Arrizabalaga appearing to struggle with a cramp as a penalty shootout loomed to settle the E.F.L. Cup final, Chelsea Manager Maurizio Sarri summoned a substitute from the bench to replace him.
Kepa was furious.
Wildly gesticulating with his arms, Kepa, the world’s most expensive goalkeeper, forcefully indicated to Sarri that he would be ready to face penalties against Manchester City with the final locked at 0-0 and extra time about to end.
But Sarri was determined to bring on Willy Caballero, who saved three spot kicks in the 2016 E.
