Former Celtic striker Sutton criticised Warburton following their goalless draw to Ross County.

That result came after a 5-1 drubbing from rivals Celtic in the Old Firm derby last weekend.

Asked about Sutton's criticism, in which the 43-year-old said "they had their pants pulled down by their biggest rivals and he’s coming out moaning about negativity", Warburton said he had taken no notice of it.
