Celtic manager Neil Lennon was left furious with referee Bulent Yildirim after a late penalty denied them all three points against Udinese in their Europa League clash at Parkhead.
Ki Sung-Yueng had put the Hoops ahead from the spot before Gary Hooper was controversially adjudged to have tripped Piccoli Neuton, allowing Almen Abdi to convert the spot-kick.
"It's a shocking decision," said Lennon.
"It cost us three points which we deserved against a very good side. We kept our discipline well and their goalkeeper made some wonderful saves.
"The referee was looking right at it and it's really hard to take."
Celtic travel to Hearts on Sunday in the SPL.
