Sarri reasserts power, benching Kepa and beating Tottenham

LONDON - Maurizio Sarri reasserted his authority on the sideline, and so did Chelsea on the field.

After Kepa Arrizabalaga refused to be substituted in the League Cup final, Sarri was determined to send a message to the world's most expensive goalkeeper by dropping him from the lineup for Wednesday's match against Tottenham.

"Kepa made a big mistake," Sarri said. "He had to pay for it."
