Scott Brown insists Celtic will not be guaranteed the Scottish Premier League title even if they take a potential 23-point lead over Rangers.
Neil Lennon's men have won 18 domestic games in succession and victory over Dunfermline at home on Wednesday night and a win over Motherwell at the weekend would give Celtic that massive advantage over the champions before the administration-hit Ibrox club travel to Inverness on Sunday.
Hoops captain Brown believes he is playing in the best Celtic side since he joined the club in 2007 and feels they are still improving.
But the 26-year-old midfielder, who signed from Hibernian for £4.4million five years ago, is taking nothing for granted in the title race.
He said: "I think it is the best we've played and it's the best bunch of lads as well. I've said that since the start of the season.
"We have been getting better and better and getting more confident each and every game. But the title is definitely not won until somebody gets the trophy.
"I think it would mean a lot to the lads [to be 23 clear] but it is definitely not over.
"It would take a lot [to lose it] but it has happened before, we have been 10, 12 points clear and we have had it clawed back.
"So there is still a lot to play for.
"We are on a good run and we want to keep it going and have a big game against Dunfermline."
