SEAN Dyche insists he has no interest in a referee's background, despite UEFA putting one of their most experienced officials in the middle at Turf Moor tomorrow night.

Burnley's 3-1 first leg defeat to Olympiakos in Athens was marred by controversy, with the hosts awarded a controversial penalty by Slovenian referee Slavko Vincic in the second half, for which Ben Gibson received a second yellow card.

Dyche was critical of the decision after the game and the intimidation of the referee he witnessed in the tunnel at half-time, with Olympiakos players, staff and officials unhappy at seeing their side have two penalty appeals waved away in the first half.

For the second leg at Turf Moor UEFA have appointed Hungarian Viktor Kassai, who has been a FIFA international referee since 2003 and took charge of the 2011 Champions League final.

Of that decision, Dyche said: "We all question referees but that’s just a different side to (Europe). They all ref in different ways, with different styles.

"Maybe UEFA looked at reports and thought hmm, maybe not as good as what we hoped.

"It’s a fine line for the manager. You have to question refs at the right times but also leave them alone to do the job.

"I always say the toughest three jobs on a matchday are the two managers, liked or loathed, and the referee.

"I just tried to state facts about the game at Olympiakos.

"I don’t look at a referee’s background, I just want them to officiate right and proper."
