If Andy Carroll is passed fit, Krul knows he will be facing a formidable forward line, with the former Toon striker forming a blossoming partnership with Luis Suarez.
"Andy and Luis Suarez are two big players and to see them together is amazing," said the goalie.
"To see Andy again and face him would be good. We faced each other this season for the U21s.
"Suarez has been great at Liverpool and was at Ajax.
"Since he came to England he has been great straight away and it will be a hard game at Anfield.
"Suarez can score from anywhere. All of his goals have been pretty special. When I have spoken to my friends from the U21s or from Ajax they do not know how he does it," he said.
"It looks like he is taking a bad touch on purpose, but he has the speed to go round people.
"He is dangerous. We have to make sure we are ready for him."
