Kris Commons is confident Celtic's three signings this summer, Kelvin Wilson, Adam Matthews and Victor Wanyama, have strengthened the Hoops enough to challenge Rangers dominance as SPL champions. 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.
"Competition for places has never been so strong, especially across then 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."
