The Swansea goalkeeper was a constant target for the green laser pens in an attempt to put him off as the home side chased a 5-1 deficit from the first leg. And despite the announcements from the stadium announcer the lasers continued through the game although I guess that it must be difficult to single out two of three people in a crowd of many thousands.

Even Michael Laudrup admitted after the game that it would be difficult to single out people either before or during the game but you could sense his own frustration while he was saying it.

And clearly the lasers had got to Tremmel as he explained to the Western Mail “It was pretty much the whole game, it wasn’t constant but every few minutes someone pointed one at me.

“I think there were two or three different ones, from both stands.

“And once it hits your eyes you just can’t see anything; they are powerful.

“I would see them flash across and then it would hit directly. It was bad.

“Obviously as soon as you move it stops because they would have to be a pretty sharp-shooter to keep up with you moving, but it is in your head.

“You are trying to organise your defence at a corner, but you notice it happening.

“It’s quite nasty and not something that should be happening in a stadium.”

Tremmel didn’t want people banned should they get caught but it is difficult I think to agree with that. Something like this shouldn’t happen and although it may be close on impossible to catch people if they are caught then they should get the three year ban treatment that is handed to people who go onto the field of play.

“I wouldn’t want to say people should be banned for it, but it should be out of the stadium.” added Tremmel

“Uefa need to find some way to deal with it, whatever that is.

“It is meant to be a football game, not a laser shooting game.”

Thankfully this is not an issue that seems to hit the game in this country but it is a frustration definitely and one that needs some thinking about
