"There's always that worry when you lose a position but I've always had faith in my ability to manage at this level," said the Welshman.
"I've had 270 to 280 games at this level, so I know what it's about. Obviously the last 12 games at the beginning of last season (with QPR) didn't help.
"That's the recent thing in people's minds and at the moment it seems people want to judge me on that period.
"I would just say to look a bit deeper than that and understand that, given the right support with the right people around me, then I can make teams successful and play well."
