Barry Robson says his best years are ahead of him after completing his £1m move to Celtic.
Robson says he has yet to reach his peak as a player
Speaking after sealing his switch from Dundee United, the midfielder said he aimed to force his way into manager Gordon Strachan's first-team.
"Celtic says it all, the size of the club, the competitions you are playing in. I just want to be part of it," the 29-year-old said.
"I feel as though my best years are ahead of me."
Robson, who is cup-tied and will miss making his debut against Kilmarnock in the Scottish Cup on Saturday, has signed a contract until 2011.
"I feel as though my best years are ahead of me, every pre-season I come back feeling fitter and stronger," he said.
"I am looking forward to the next three-and-a-half years - I feel my body is getting stronger as I go along."
Robson said he hoped his versatility would help him to force his way into the first-team.
"I think I can play centre, left or right, I'm comfortable playing any of them," he said.
"If I get the chance and do the business, I will stay in the side, it is the same at any club.
"But I am under no illusions, I know how good Aiden McGeady, Shunsuke Nakamura, Paul Hartley, Scott Brown are from playing against them."
The former Rangers player - who scored 12 goals for United this season - had also been the subject of a similar bid from Nottingham Forest this week.
But the midfielder, who began his career at Ibrox before moving to Inverness Caledonian Thistle, opted to join Celtic.
