Krul: Glory times returning at Newcastle
Krul is sure his team-mates can give their loyal supporters some needed cheer.
Krul, 24, said: "It's incredible where we are in the table. The good times are back - just keep believing.
"Bolton at home on Monday is a big opportunity. Hopefully we'll have a sell-out crowd and can get a victory.
"We have to win to keep the pressure on the top four."
