Neil Lennon is wary that a hungry Hibernian will wreck Celtic's unbeaten run in their Scottish Premiership clash on Sunday at Easter Road.
Lennon's team have gone on an incredible run of 21 games unbeaten, with eight successive clean sheets and 10 consecutive wins in the league.
He told the Celtic website: "Our players are very motivated to keep the run going, but then I'd say the opposition is motivated to be the team that stops the run.
"Every game is a challenge in itself and has a little bit more edge to it the way things have panned out over the season."
Lennon was involved in his own outstanding run of consistency when he played for the Hoops, but that won't stop him willing his own players to equal, and then better Martin O'Neill's record from 2003/04.
"I think it's superb, the consistency that they've shown," he continued. "I think the last run we've been on like this was 10 years ago when I played under Martin O'Neill - we drew our first game against Dunfermline and won our next 25.
He added: "We've got to get towards 26 or 27 before we can start comparing those runs, so we've got a bit of work to do first.
"What I'm looking for is obviously improvement all the time but they're playing at a very good level just now, their last two performances have been superb."
