Former Rangers midfielder Neil McCann believes Celtic's attacking style leaves them open to defeat against Malmo, but predicts they will do enough to go through.
Celtic edged the Swedish side out 3-2 at Parkhead in the first leg, but the away side's late goal from Jo-Inge Berget put a different perspective on the return fixture, as opposed to if the game had finished 3-1.
The two away goals mean a 1-0 win or 2-1 win will be enough for Malmo to progress, although a draw will be enough for Celtic.
Former Rangers midfielder McCann told SkySports Morning View, broadcast Monday 24th at 11am, that the side's attacking approach leaves them too open at the back.
He said: "Ronny Deila plays a real open game of football. The full backs are so advanced it exposes the centre-backs.
"I was amazed Berget was left unmarked ahead of goalkeeper to score."
The strike from former Celtic forward Berget certainly will give Malmo more belief they can reach the group stages, but McCann believes ultimately the Scottish side should have enough strength to qualify, but knows it will be far from straightforward.
Deila's side would be advised to play to their strengths, but also adapt to a more cautious defensive approach especially early on in the match.
He added: "Malmo scores lots of goals at home. They are 20 games into the season and at full speed already. I still believe Celtic have enough to go through though."
