Recent Celtic signing Kris Commons knows their games against Rangers will decide their season.

The Scottish Cup replay against Rangers is scheduled for March 2 but before that the Light Blues visit Parkhead on SPL duty, while the Co-operative Insurance Cup final between the two Glasgow giants takes place at Hampden next month.

"The games against Rangers will be tough games," Commons said.

"You can't go in there with an arrogance or be too confident because they are a dangerous side and they showed that at the weekend.

"They could have been two-nil up after five minutes so it could be a completely different game and a completely different outlook from the press point of view.

"But the fact that we did so well in the second half with 10 men has put in people's minds the idea that we have the ascendancy.

"We are fully aware that we are capable of winning the treble but we have to approach every game in the manner that we do at the minute and that is give 110%, work hard and then hopefully our football will come through."
