Rangers boss Mark Warburton has brushed off comments made by Celtic captain Scott Brown.

Brown claimed on Monday that Aberdeen and Hearts were Celtic’s main rivals for the Premiership title, but Warburton says those comments will not bother his side.

Talking on Sky Sports News, cited by the Aberdeen Evening Express, Warburton was asked if the Parkhead midfielder’s comments had affected his players.

“Not at all. Football is a game of opinions,” Warburton said. “Scott is a very experienced player, he has put forward his opinion. All we do is put forward ours.

“We know where we are, we know how prepared we are, we know how tough a challenge it is going to be but as I say, enjoy opinions, discussion points, that’s what the game is all about but we know where we are, that’s for sure.”

Celtic are aiming to clinch their sixth consecutive Scottish Premiership title but are expected to face a tougher challenge with Old Firm rivals Rangers returning to the top-flight.

Rangers were the last side to stop their rivals winning the domestic league trophy and will be striving to do so again after they lifted the Scottish Championship last season with 81 points.

Aberdeen will feel confident going in to the new league campaign as they finished runners up and gained qualification to the Europa League qualifiers, although they were still 15 points adrift of champions Celtic.

Rangers have heavily bolstered their squad this summer by signing former Premier League stars Joey Barton, Clint Hill and Nico Krancjar.

Barton is set to go head to head with Scott Brown at the heart of midfield and they have already exchanged words about the rivalry this summer.
