Three years ago, Cusiter was the man in possession of the Scotland No. 9 shirt and was one of the few Scots to go on the last Lions tour to New Zealand. 

But since Frank Hadden took over as Scotland coach he has had to play second fiddle to Mike Blair, who barring injury is poised to take the role for the whole of the RBS 6 Nations - which starts this weekend - after being named captain. 

But Cusiter, who played for the now defunct Borders team, is hopeful that being back in Scotland from next season will work in his favour in the lead-up to World Cup 2011.. 

He said: “I hope to bring the experience I’ve gained over the last two seasons to an already very talented Glasgow squad. 

“I believe it’s the right time to come back to Scotland. I’m looking forward to earning a starting place for Glasgow which, in the long run, may also help my international aspirations as we look forward to the Rugby World Cup in 2011.”
