Celtic's summer signing Joe Ledley is relishing playing in his first Old Firm clash against Rangers on Sunday.
The former Cardiff City midfielder has made a bright start to life at Parkhead, although their biggest test lies ahead this weekend.
Both teams have made perfect starts to the campaign and something must give when the joint leaders go head-to-head.
Celtic got the better of Dundee United late on last time out and Ledley believes the three points stand them in good stead.
"I am buzzing about the game," said Ledley. "I know it is a massive game and I can't wait to get started.
"Some of the boys down at Cardiff just now have played for the Old Firm clubs and they all say it is a great atmosphere.
"It was a massive result for us against Dundee United because we were under a bit of pressure after Rangers won on Saturday.
"We played really well and went at them straight from the first whistle and could have been three or four goals ahead by the end of the first half.
"It went to the last couple of minutes but the game should have been over by the break due to the amount of chances we had.
"With the players and management team we have, we can dominate most teams in this league."
