BY any reasonable expectation at the start of the season, Ange Postecoglou has overachieved somewhat this term by managing to win a double.

That doesn't mean that he can rest on his laurels though, as former Celtic manager Martin O'Neill was only too keen to point out during the week.

The pair met at the Celtic FC Foundation's Annual Gala in London on Thursday night, and after congratulating him on his achievements during his first season at the club, O'Neill reminded Postecoglou of the tough acts he has to follow.

"He mentioned that he won a Treble in his first year!" Postecoglou said. "I only won a double. It’s all good.

"That’s the beauty of this football club. You don’t need to look anywhere else for motivation or inspiration. It’s a club which is built on success and great deeds.

"All of us who get the opportunity to serve the club, you want to set your own mark and try to emulate the feats of the great people who’ve been at this football club.

"I just find it inspiring and motivating that the legends of this football club have set those standards.

"It’s up to me and the people who work with me and the ones who come after me to try and maintain those standards."

Postecoglou says he has been blown away by the reaction to him from supporters he has encountered in the whirlwind few days since they ensured they would be Premiership champions.

"It helped that we’d won the title," he said. "It might have had a different feel if we hadn’t got the result the night before.

"The Foundation does unbelievable work. The people who support it and run it are unbelievable in terms of their efforts.

"It was a great night because it was for such a great cause and it was great sharing that moment with people who love this football club.

"It’s been pretty full on. But it was great to the support the Foundation and it was great to see the legendary Martin O’Neill there and spend some time with people. But I had to get back up here for training so it was a bit of flying visit.

"I’d bumped into Martin a couple of times before very briefly. He’s always been very kind and it was great to catch up with him and have a bit of a chat. He’s a great man."
