Vladimir Petkovic has admitted that the referee cost his Lazio side as they went down 2-0 to Fenebahce on Thursday evening.
A controversial penalty and a late Dirk Kuyt strike gave the Turkish side the victory, but the Biancocelest boss believes that the Scottish official, who sent off Ogenyi Onazi, was to blame.
“We did not deserve this sort of treatment,” he told Sky Sport Italia. “But now we have to roll up our sleeves and think about the match against Roma [next Monday].
“We are still not out of the competition, but of course, the referee has had an influence on this game.
“We still believe though. Not having Onazi or Mauri will affect us a lot.
“But with intelligence and belief we can overturn this result.
“We will give everything to go through.”
