Andre Villas Boas's side and the Bulgarian champions have been sharing a pre-season training camp in Austria, so decided to make the most of it and face each other in a practice match.
It appears the pitch may have been double-booked though, because 14 minutes in a squad of local ducks rocked up.
The ref did manage to get them off the field, but (you know how ducks are) a couple of minutes later they were back again. This yobbish behaviour, coupled with some pretty torrential rain, meant the game was abandoned at half time with the score 0-0.
Fancy seeing the duck-heavy highlights package? Here you go.
Quackers (sorry).
