Rangers will go 10 points clear at the top of the SPL with a game in hand if they beat Celtic on Sunday, but Lee McCulloch insists the second-placed side are favourites for the Ibrox clash. Rangers midfielder McCulloch insists Celtic's January spending spree has given them a stronger chance ahead of the third Old Firm derby of the season.
McCulloch said: "We're not silly enough to forget that with the next game everything can turn again, so we just need to keep doing what we're doing.
"I think Celtic have to be favourites to win the game with the players they have brought in.
"With the rest of the signings I think they have around six strikers, and some good players, but we will not be rolling over. We'll be up for the challenge, that's for sure."
