Sunderland boss Martin O'Neill is demanding better from on-loan Arsenal striker Nicklas Bendtner.

The Dane has scored just three times in 15 appearances since his arrival in September, and issued a grovelling public apology for his extra-curricular antics before Christmas.

O'Neill said: "There'll be something [on Saturday] morning again about Nicklas being arrested in October, and I wouldn't be surprised on Tuesday if he's arrested in Copenhagen.

"Don't get me wrong, I'm not treating it lightly if it's anything serious. I learnt about this incident this morning.

"What I want is for him to perform on the field, and to do less performing off it. That would be brilliant. It's called behaviour."
