Celtic manager Ronny Deila has expressed his disappointment with his side's 3-1 defeat at Molde in the Europa League, but reserved his sternest criticism for midfielder Kris Commons.

Strikes from Ola Kamara, Vegard Forren and Mohamed Elyounoussi fired Ole Gunnar Solskjaer's team to victory in Norway, despite a second-half goal from Commons.

The 32-year-old appeared unhappy when being substituted in the 76th minute, aiming a number of angry-looking gestures towards the Bhoys bench.

Deila told BT Sport after the game: "I am very disappointed. I expected a much better performance.

"[Kris Commons's reaction] was unacceptable. That's something we can't have. Everything is about the team, not one player.

"We need to beat Molde at home then there could still be a chance [of progression] and that's positive."

The result sees Celtic slip to the bottom of Group A.
