The 27-year-old Newcastle goalkeeper hadn't put a foot wrong before his injury - but could still be at risk of losing his guaranteed starting place.
This time around, however, the Dutchman upped his game - and was pivotal in some games where things could have gone a lot worse for the Magpies.
His knee injury, picked up on international duty and ruling him out for the rest of the season, was therefore a big blow for Newcastle and their fans.
But, as things have transpired, Newcastle have done just fine without Krul. And could the 27-year-old even be in danger of losing what was a guaranteed starting place when he comes back from injury?
Indeed, for the same reason the Magpies might not have been interested in signing Victor Valdes (although Manchester United's unwillingness to loan to a Premier League rival might have also had something to do with it), Krul might not be needed next season - through no fault of his own.
Rob Elliot has just been that good for Newcastle. Having bided his time and remained patient in the wings at St James' Park, Elliot is now no.1 on Tyneside and often wins matches with his top-drawer saves and performances.
So why should Krul walk back into the side when he returns from injury? Elliot has been top class.
