Ter Stegen celebrated his 28th birthday on Thursday, and has emerged as a credible rival to Manuel Neuer with the Germany national team.
He has lifted a remarkable 14 trophies for club and country – 13 for Barca and the Confederations Cup for Germany – since leaving Borussia Monchengladbach in 2014.
Yet Masip is aware there is another strong contender in Spain to be considered the world’s premier shot-stopper: Atletico Madrid’s Slovenia international Jan Oblak.
“Oblak is also in great shape, he is another great goalkeeper,” Masip said.
“They are two goalkeepers who are in the teams they have to be, they fit perfectly with their respective teams. They’re two great ones. They help all the other goalkeepers to look and improve.”
A pair of Brazilians, Liverpool’s Alisson and Manchester City‘s Ederson, have also persuaded 31-year-old Masip of their top-level qualities.
The pair have impressed in the Premier League and Champions League alike in recent seasons.
“I also like Alisson and Ederson, the Liverpool and City guys,” Masip added. “They came in young, with a lot of desire, they are good and their performances have been reflected in the results of their teams.”
