Celtic fans are prepared to give Ange Postecoglou time, according to former Hoops midfielder Stiliyan Petrov.

Postecoglou suffered a sixth away defeat in charge on Sunday to leave Celtic sixth in the Premiership table.

The Hoops have lost all three of their away games in the league but the run without a domestic triumph on the road stretches back seven months, when Neil Lennon was still in charge and before John Kennedy's extended caretaker stint.

Celtic made 12 summer signings and Postecoglou was without the likes of skipper Callum McGregor, top goalscorer Kyogo Furuhashi and new signing Giorgos Giakoumakis for the 1-0 defeat at Livingston.

With vacancies in the chief executive and chief recruitment roles adding to the state of flux, Petrov feels a slow start was inevitable this season.

"Everyone is talking about the away form," he told Sky Sports. "It's just a transition period they have to go through.

"Ange is finding it very difficult to get his best team out on the pitch, he is finding it very difficult to pick his best players.

"It will take time. It's a transition I think everyone expected.

"I think fans are quite satisfied with what's going on on the pitch and it's just one of those periods they have to go through.

"The way the manager wants Celtic to play, it's very difficult. There's a lot of details need to be covered.

"He always stresses how he loves going forward and loves scoring goals but they have got a lot of new players at the back and they need time to gel.

"There's a lot of work that needs doing on the pitch, he knows, and he is talking about it. He is quite calm and he knows the process will take time."

Celtic fans were given tickets to an away game for the first time since 4 March, 2020

Petrov signed for Celtic in the early days of John Barnes' reign in 1999 and helped the new manager to 12 wins in his first 13 matches in charge.

But Barnes was gone by the middle of February 2000 after a Scottish Cup defeat by Inverness came on top of three league games without a win.

When it was pointed out to him that time is not a luxury afforded to managers in Glasgow, Petrov, speaking at a John Hartson Foundation golf day, said: "I believe when the new manager was appointed with everything on the board with the chief executive and director of football, I think everyone understands, especially the fans, that the club is going through a change, a transition, that needs time, needs patience.

"I know you stressed there is no time if you don't win but I think the Celtic fans are quite prepared to give this manager time and at the end of the season they will analyse it."
