Raheem Sterling scored a 96th-minute victor as City defeated Saints 2-1 and, bizarrely, after celebrating the goal, Guardiola marched over to an unsuspecting Redmond and proceeded to lay into the 23 year-old, even tapping his hand on the player's chest.
"What Redmond said in his statement, I admire him as a player and thank him for his comments", he added.
"I told Redmond that he is a good player; last season he destroyed us with his style, but this time he could not attack us because his team was always in a defensive position, they wasted a lot of time during the game", Guardiola explained at the press conference.
Guardiola was predictably asked about Redmond on Friday, with the manager having been asked by the FA for an explanation as to his actions. What I said is what I said and what Nathan said in his statement.
The Spaniard added: "I can not control myself". If they don't believe me I don't know what we're doing here.
Moments after the full-time whistle, Guardiola looked raging with the Southampton ace as he shouted in his face and pushed the winger. "I never judge and never will judge the way my opponents play against my team. It's the same as I do to beat them".
"Nothing negative or offensive was said towards me from Pep and that's what makes him one of the best managers in world football". Sterling also struck twice in added time in August, hitting a victor at Bournemouth and an equaliser against Everton in the only match this season rampant City have not won.

That followed a similar, injury-time victor at Bournemouth and a point-saving late equaliser with Everton, the only team to have avoided defeat against rampant City this season.
