Kris Commons believes experience is the only trait Rangers hold over Celtic but admits their rivals are worthy Scottish Premier League winners.
Celtic won the Scottish Cup on Sunday with a 3-0 victory over Motherwell, a mere consolation for the club who lost the league title to their Old Firm foes by one point last weekend.
The Bhoys also missed out to Rangers in the Co-operative Insurance Cup final in March but Commons, a January signing from Derby, believes this season will make them stronger.
He said: "Rangers are a good side, they have good players and have experience in Davie Weir, Sasa Papac and Allan McGregor, but we have to concentrate on what we do next season.
"We have a young squad and this sort of experience will make us stronger.
"When you look at the average age of our squad - Beram Kayal, Gary Hooper, Anthony Stokes, Emilio Izaguirre and Charlie Mulgrew - they are all 22, 23 or 24, at the top of their game and international players.
"But you can't buy experience and Davie Weir got them (Rangers) rallied up and rightly so took them to the title because overall this season, they have been the better side."
Commons, who earlier this year claimed Celtic were "younger, fitter and stronger" than their Glaswegian neighbours, stands by his stance despite being pipped to the post in two out of three domestic competitions.
"I think when we are on song, we are untouchable," he said. "We beat Rangers 3-0 (in the SPL) and we were far better than them.
"But (then) we go to Inverness and we collapse and we went to Motherwell and collapsed.
"I don't regret saying we were younger, fitter and stronger, I still believe we are."
