Supporters of the Swedish side sang ‘Hey, Celtic, leave those sheep alone’ instead of the recognised lyrics ‘Hey, teacher, leave those kids alone’.
The sing-song was captured on video and uploaded to YouTube and Facebook ahead of the clash that finished 3-2 to Celtic after ex-Hoops player Jo Inge Berget netted a late goal for Malmo to ensure the tightest of scorelines ahead of the return leg in Sweden.
We’re not quite sure why Malmo fans chose that particular song to try and ‘troll’ the Celtic support.
Aberdeen fans are normally on the receiving end of the sheep banter, with some even going so far as to wear sheep masks to matches.
On a slightly related note, we did find this photo of ex-Don Richie Byrne at Pittodrie having an inflatable sheep thrown at him.
