Celtic fans are delighted on Twitter to see former goalkeeper Rab Douglas has decided to extend his lengthy career by joining Arbroath.

The 44-year-old has signed with the Scottish League Two side after quitting Forfar in December 2015, and is likely to feature in their Scottish Cup clash against the University of Stirling on Saturday.

Arbroath revealed the news on their official website, after number one goalkeeper Robbie Mutch was ruled out in featuring in the second round tie.

Douglas was a permanent fixture in between the sticks at Celtic Park for five years after signing with the Hoops in 2000, and made a total of 162 appearances for the 47-time Scottish Champions.

Celtic fans have reacted on Twitter in delighted fashion after seeing Douglas had signed with the Scottish minnows, with many shocked that he is still around.
