Krul, who is likely to be rested for Thursday’s final group qualifier in Bordeaux, knows Alan Pardew’s side are desperate to end the club’s long wait for silverware.
He said: "We've already achieved one thing which is qualifying for the Europa League.
"We wanted to stay in that, we're in the last 32 and it's a great competition to be in. We're the first English team to do it.
"Is it important to get the top spot? Yes and no. I think I've heard Jose Mourinho say that every time he's won the Champions League he's finished second in the group."
