The ex-Celtic attacker has stated how he thinks Ronny Deila’s side should prepare for their upcoming cup semi-final clash.
The perennial rivals come face to face for the first time since the League Cup semi-final encounter in February 2015 on Sunday when they meet at Hampden Park for the Scottish Cup semi-final.
Rangers were demoted to the bottom rung of the Scottish football League back in 2012-13 but have fought their way back up to the top table with three promotions in four seasons.
Next season we should expect at least three encounters between the two heavyweights north of the border due to Rangers' promotion to and this match could prove to be a delicious appetiser for what is expected to be a largely competition top-flight division next term.
Ahead of the battle in Glasgow, former Celtic forward McAvennie - who scored 37 in 85 across two spells with the Hoops - claims Deila’s side should look to find space in behind their rivals’ offensive wide defenders.
He is quoted as saying by the Daily Mail: “Whenever Paul McStay or somebody like that ran by me I used to fill in for them. I don't see anybody helping the full backs at Rangers.
“They bomb forward and I don't see anyone chasing to fill that gap. I think everyone's just going: 'I'm in my own wee position and I'll look after myself.
“You've got to cover your pals. The manager shouldn't have to tell you, because you should do it yourself.
“You can get away with it in the Championship. They won't get away with it when they come up next year. And they can't leave these two centre-halfs against Leigh Griffiths - especially if (Kris) Commons plays, because he'll find them and he'll destroy them.
“James Tavernier and Lee Wallace both bomb forward. Normally one should go forward and the other sits in. And they've got one full back crossing the ball and the other full back's getting on the end of it!
“It's good to watch for the supporters but there are only certain times you can do that. You can't do that against teams like Celtic because they will punish you.
“If I was a Celtic striker now I would fancy my chances on Sunday.”
