Kepa Arrizabalaga is used to things happening fast. Aged 23, he had made 53 La Liga appearances when Chelsea made him the world's most expensive goalkeeper in the summer of 2018. Athletic Bilbao finished a modest 16th place that season. Kepa had one international cap for Spain, earned in a 5-0 friendly win over Costa Rica. Despite possessing more potential than proven pedigree, the Blues handed him a seven-year contract in a remarkable show of faith for a club famed for its capriciousness.
Just two years later, Kepa is losing the battle to save his Chelsea career as head coach Frank Lampard harbours mounting doubts over whether he will ever become robust enough to form the first line of defence in a Premier League title-winning team.
