Celtic manager Ronny Deila has said that attending Premier League matches is boring, compared to watching Scottish Premiership action.

He also believes that Scottish fans should be "more proud" of the Scottish Premiership.

"The interest is phenomenal. It's something special when you go to Celtic games, away games as well, the fans are fantastic," Deila told reporters.

"I've been to many games in England and I've been bored compared to what's happening here in the stands sometimes."

Deila wants to see investment in Scottish football to help improve the quality of the Scottish Premiership.

"The product in Norway has been getting better and better," he added. "TV2 [has the rights] has made a really good impact and have built up the product," he added.

"It's quite good money compared to what a small country we are so we will get that in Scotland as well if we built up our product and don't ruin it.

"It's important to work with developing our teams that want to attack, create things and put on good performances for fans. TV and media around it should build it up because I think Scottish football has so much enthusiasm and interest."

Deila previously worked as a pundit for Norwegian television.
