The 24-year-old has established himself as Newcastle's first-choice goalkeeper and become a regular for Holland.
Martin Jol: "He is good and young.
"It will be the first time a guy like him is a regular in the national team.
"Normally we have they likes of Hans van Breukelen and Edwin van der Sar - quite old goalkeepers.
"Van der Sar probably had his breakthrough while he was here at Fulham when he was 30 or something.
"Krul is a big talent, good goalkeeper, but we've got the other guy at Swansea, Michel Vorm. He is very talented, maybe one of the most talented ones.
"Krul is versatile, big but don't forget that we've got one of the best in Europe, Maarten Stekelenburg. I had him at Ajax and he is a good goalkeeper."
