Celtic manager Neil Lennon has urged Dundee United to "compete" against Rangers in Tuesday night's crucial Clydesdale Bank Premier League clash at Ibrox.
The Hoops surrendered the advantage in the SPL title race to their Old Firm rivals by losing to Inverness on Wednesday night. However, goals from Scott Brown and Kris Commons against Kilmarnock at Rugby Park took them back to within one point of the champions.
Celtic's goal difference superiority has consequently been cut to three and Lennon is looking for United to do him a favour against Rangers, 24 hours before the Parkhead men travel to Tynecastle to face Hearts.
"We have two games to go and anything can happen," said Lennon. "What we are looking for is somebody to compete and give Rangers a game. There has not been much evidence of that in their previous two games.
"Even if we had drawn the game against Inverness on Wednesday night, I'm not sure goal difference would have made a difference, looking at the two games that Rangers have had.
"Dundee United have something to play for now (a European place). But I'm not going to cast aspersions at other clubs."
