Pat Bonner admits he fears Celtic will lose a goal every time an opponent attacks them.

The Hoops have conceded eight times in their last three games, with defeat to rivals Rangers and Sunday’s 3-3 draw with Aberdeen raising question marks over their chances of securing a record 10th successive title.

Bonner believes the champions were improved in attack against the Dons, with Callum McGregor and Leigh Griffiths netting ‘wonderful’ goals before Ryan Christie looked to have won it with his late penalty. But the legendary former Celtic keeper insists his old side are ‘all over the place’ defensively and have massive work to do at the back.

He said: “The defending was poor and that’s what cost them the three points. They were absolutely all over the place. That last goal was almost like a comedy of errors, when they should really have been in control of the game.

“They’ll be ruing that. That’s two points gone when they were in the position to win, and you don’t see that too often from Celtic.

“Celtic have gone through periods in the past, I remember when Fraser Forster was there, where they went 10 or 15 games almost without losing a goal. But, now, they look like every time somebody goes and attacks them they’re going to lose goals.
“That’s the worrying part that they’ve got to get right.

“But I think the rest of the game on Sunday was a lot better. They passed the ball well, they were slicker, and the two goals they scored were wonderful goals.”

The draw leaves on-form Rangers six points ahead at the top of the Premiership and raises doubts over Celtic’s ability to reach the Scottish Cup final when they face Aberdeen again at Hampden this weekend.

Bonner added to BBC Scotland: “[A win] would have been a huge confidence-booster for them. It would have set them up for the games coming.

“Now, they’re under that bit of pressure again and can they handle it? That’s the question.”
