Callum Wilson says Loris Karius has a point to prove in the Carabao Cup final after high-profile mistakes made the keeper's career "take a nosedive".
Karius, 29, could be in goal for Newcastle against Manchester United at Wembley on Sunday, with Nick Pope suspended and Martin Dubravka cup-tied.
The ex-Liverpool keeper was blamed for two of Real Madrid's three goals in the 2018 Champions League final in Kyiv.
"He has so much to prove to people," Newcastle striker Wilson said.
The Magpies are looking to win their first major trophy since 1969, but are without first-choice keeper Pope who was sent off against Liverpool in the Premier League on Saturday.
