Pat Bonner warns Celtic to stay alert
Former Celtic goalkeeper Pat Bonner believes Ronny Deila's team need to adopt a cautious approach against Ajax as they bid to keep their Europa League hopes alive.
Celtic cannot afford to lose on Thursday and realistically need to win to retain their qualification prospects.
After consecutive defeats to Norwegians Molde, assistant boss John Collins said that they would not change their attacking style. But Bonner feels Celtic, who drew 2-2 in Amsterdam in their opening group game, can succeed by picking Ajax off at Parkhead.
"The way Ajax will play will always give teams an opportunity," the former Republic of Ireland goalkeeper said.
"They are a young team and a bit brittle at times but they play that typical Dutch/Ajax way of expansive football.
"They are very open and if you can defend well against them, I think you can exploit the space that is left. They will throw their full-backs forward and open up, and I think Celtic can score against that type of team.
"They don't come up against it very often, especially at home, and I think if they can defend well and exploit those opportunities, they have a chance of winning. But they have to defend well.
"I've always said in Europe you have to be more cautious. You can't play the normal way Celtic play, especially under Ronny when they push full-backs forward and almost leave it two v one at the back.
"I think you've got to be a bit more adaptable and change it a bit to get a chance."
Bonner was part of a Celtic team that knocked Ajax out of the 1982-83 European Cup with the help of a spectacular Charlie Nicholas strike in Amsterdam and believes another win over the Dutch side could be just as memorable.
"That was a great Ajax team but we were decent ourselves," the 55-year-old said.
"There was a good competition in Scotland at the time: Dundee United, Aberdeen, Rangers, to a point, and ourselves. The fans were happy and Europe was a real bonus to us at that time.
"Those big nights will always go down in history, beating Ajax in Johan Cruyff's last season, nights we talk about still. That's what creates history and that's what we need on Thursday.
"If they can get through the group then everything changes, it would be magnificent. They are top of the league and have a chance in the two cups but these two games coming up are vital."
Bonner was speaking at Hampden's Scottish Football Museum after handing over a rare framed recording of 'The Laddie Frae Cardenden', a song by Glen Daly about former Celtic goalkeeper John Thomson, which was donated by the late Scottish entertainer's family.
Thomson died aged 22 in 1931 after being injured in an Old Firm game in his 188th appearance for Celtic.
