There's some shenanigans going on at CL games. (not that we need to worry about it now!)
25 mins after kick off, random Chinese lads (late teens/early 20's)
Walking up and down the aisles looking for any spare seats to sit in. My son didn't go to the Copenhagen game, and some lad just came and sat in his seat. It was the same last night. One lad was moved because the actual seat owner came back from the concourse and moved him. Then he sat on the steps and was moved on by the steward. Then he appeared on the next aisle along, doing the same thing.
I don't know if someone is letting them in for cash or they have managed to hack into the system and get the QR codes for access, but 3 CL games it has happened now.
