Is 'underestimated' Raya the best goalkeeper in the world?

Kai Havertz declared David Raya the best goalkeeper in the world after his saves helped Arsenal secure a 1-0 win over Sporting in their Champions League quarter-final first leg in Lisbon.

Havertz scored the decisive goal, controlling a pass from fellow substitute Gabriel Martinelli and finishing coolly in the 91st minute, but he was eager to praise their goalkeeper's contribution.
