CELTIC are more than capable of challening Rangers for the Premiership crown this season.

Thats because Ange Postecoglou shows great adaptability in his management skills.

Former Hoops ace Charlie Nicholas has been generous in his praise of the Australian boss, admitting he's a member of the Postecoglou fan club after watching the weekend win over St Johnstone.

Nicholas, who has previously been critical of Celtic's approach under the new boss, is now convinced his old side are genuine title challengers.

Nic revealed he was impressed with how Celtic dealt with Saints' defensive set-up and that's why he thinks the team is now heading in the right direction.

Nicholas wrote in the Daily Express: "I became a fully paid-up supporter of Ange Postecoglou's Celtic at the weekend.

"I was back in the Parkhead stands on Saturday with two of my brothers-in-law for the win over St Johnstone.

"It was my first time in a while after TV commitments and everything else. I have always wanted to get back to the games with all the changes that have happened at Celtic.

"The team is definitely heading in the right direction.

"I had always said it would be October or November before we can really judge Ange.

"I know Ange suggests he only has a Plan A but I do think he has other options in his head. I wanted to see his team for myself and how he is trying to piece all these new signings together.

"I really do think Celtic can squeeze Rangers all the way in this Premiership race.

"I still think that Rangers are favourites but I like what the new Celtic boss is building.

"Rangers are ahead in the table and they also have key players coming back.

"They are more solid and because of that they have the advantage over Celtic.

"But I can definitely see this Celtic team clicking and challenging Rangers. I saw that first-hand at the weekend.

"Celtic didn't excite all the time but they were up against a St Johnstone who didn't want to come out."
