The world's two most expensive goalkeepers meet at Anfield on Wednesday night, but while one is a newly crowned Premier League champion, the other is under mounting pressure to prove he is worth the fuss.
There were 20 days separating Alisson's arrival at Liverpool and Kepa Arrizabalaga joining Chelsea, the baton and burden of costing more than any shot-stopper before them quickly passed before a ball had been kicked. Alisson's £66.8 million fee was usurped by the £71m release clause the Blues triggered to sign a then-23-year-old from Athletic Bilbao who was not even first choice for his national team, with David de Gea clinging to that position despite his own travails at Manchester United.
