Tim Krul
The Newcastle goalkeeper has finally put his injury demons behind him following a loan spell away from Premier League new boys Newcastle with Dutch outfit AZ Alkmaar this season.
An eight-time Holland international, Krul has huge experience in the Premier League with 42 clean sheets in 157 top-flight appearances but could now be set to leave St. James’ Park this summer.
Rafa Benitez has an abundance of goalkeepers available to him with Krul competing alongside Matz Sels, Karl Darlow and Rob Elliot, and that could see Krul leave and Celtic potentially profit.
