As the battle between Red Bull and Mercedes continues to heat up, Nico Rosberg thinks the relationship between Toto Wolff and Christian Horner will continue to be frosty.
Red Bull sit atop the Drivers' and Constructors' Championship following Max Verstappen's victory in Monaco, but with the debate over flexi wings looking like it will take centre stage in the coming weeks, Rosberg senses Wolff isn't all that pleased with his counterpart after he told Sky Sport Italia he'd rather be battling with Ferrari than Red Bull.
"That wasn't very nice of Toto to say," Rosberg told Sky Sport Italia. "I think Wolff doesn't like Horner very much because he's not always that, shall we say, sympathetic to him.
"You are really going to see a tug-of-war there now because Mercedes says they are going to file a complaint, a protest and so Red Bull is going to do the same.
"It's going to be a real thing when all that happens next race, I'm really curious how it's all going to work out. It might happen before Baku, so that keeps everybody in suspense."
