Celtic captain Scott Brown insists extending his contract was never in doubt despite a lengthy delay in finalising the deal.
Brown announced that he had agreed terms in August but an impasse over a fee for his agent meant the contract wasn't signed until Saturday.
"I knew Celtic was the only club for me," said Brown.
"I knew it would happen eventually. It was up to the club and my agent. I don't really take part in that."
The 26-year-old Scotland midfielder is now committed to Celtic until the summer of 2015, with the club having the option of adding a further 12 months to the deal.
Brown said that he had not been approached by any other clubs and would be happy to end his career at Celtic Park.
"I'd be glad to stay here," he added. "It's a great place to play football.
"We've got a great training ground, great players and a great manager.
"I enjoy playing here and I'm going to win trophies. If you go down to England, you might not get that.
"I enjoy winning and that's why I signed for Celtic."
Brown has made two appearances as a substitute since recovering fully from an ankle injury and knows he will need to work hard to reclaim his starting place.
"I've only played 30 minutes of football in the last seven or eight weeks, so I need more games.
"There's a reserve game tomorrow, so I'll hopefully get 90 minutes under my belt.
"The lads have been flying and we've managed to catch up a few points [on Scottish Premier League leaders Rangers]."
Celtic paid Hibernian £4.4m for Brown in 2007, a fee that remains a record between two Scottish clubs.
