Ex-Wolverhampton Wanderers manager Stale Solbakken has said he would never return to the Championship, describing the division as "brainless."
Solbakken, who spent six months in charge at Wolves in 2012-13 before being sacked after 30 games, is preparing his FC Copenhagen side to host Leicester in the Champions League on Wednesday.
He said: "I am one of the longest-serving [recent managers at Wolves]. I wouldn't do it again.
"It's a difficult league to manage in, when the crowd are managing many of the games and they want to see chances. I have seen so many brainless Championship games.''
Copenhagen are five points behind Group G leaders Leicester after a 1-0 defeat at the King Power Stadium last month and are aiming to stop the Foxes winning at Parken and reaching the round of 16.
Solbakken added: "When it is a home game we maybe have to risk something more than we did in some periods at their stadium.
"We controlled the game but maybe we had to risk something more. But their counter-attacking ability is such that our way of dealing with that has to be improved.
"We know we have had many historic nights in the Champions League -- we have beaten better teams than Leicester and lost to worse teams."
