Manchester City defender John Stones doesn't expect any aggro between manager Pep Guardiola and Manchester United's Jose Mourinho.
Stones reckons it won't overshadow things when Manchester United face City.
He said: "That's another big debate that's been about, but I'm sure they'll show their respect to each other.
"They're two very respectable men, who've done a lot in the game, and we'll just have to see how it pans out, but I'm sure they'll be respectful to each other, whatever happens.
“It's not only going to be a tactical game but a technical game, with a lot of heart on everyone's sleeves I suppose, so I'm trying to take in as much as I can this week to prepare myself for the game."
