Kris Commons believes Celtic are well-equipped to end Rangers' grip on the Scottish Premier League trophy this season.
The Hoops have made three additions to their squad this summer, with Kelvin Wilson, Adam Matthews and Victor Wanyama brought in to fight for places in defence.
Manager Neil Lennon is searching for a goalkeeper to replace Fraser Forster, with Croatia international Stipe Pletikosa aiming to win a contract.
South Africa striker Katlego Mphela, 26, is also expected at Lennoxtown for a trial next week.
But Lennon is generally happy with his squad after they gelled following a summer of major upheaval last year.
And Bhoys winger Commons believes there is ample competition for places to keep everyone at the top of their game as Celtic look to stop Rangers claiming a fourth consecutive championship.
The Scotland international said: "I think we showed some good performances last year and the best players are still here with us. The new additions have made us a better squad.
"Expectations are high on both parts, from the fans and ourselves and the coaching staff.
"I know the management are all looking to improve the squad and there is no point buying just for the sake of it.
"We will bring players in who are only going to improve our squad. The people who have come in have certainly done that."
He added: "Competition for places has never been so strong, especially across the midfield and back four.
"So, if you're not quite performing at your best you know you're going to be missing out on the next game.
"It keeps us as hungry as possible and hopefully good things will happen this year."
