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.
"(I told him) how good a player he is", Guardiola said.
"It was a good night, I think all the supporters create some special moments tonight and in the last second we enjoyed the situation", the City boss told a new conference.
Guardiola admitted frustration that Southampton "didn't want to play" and "were time wasting from the ninth minute". I can not control myself. What I said is what I said and what Nathan said in his statement.
Redmond's comments support Guardiola's version of events, with the manager insisting he had not been critical of Redmond in their animated conversation. If they don't believe me I don't know what we're doing here.
Conor McGregor receives £350 fine for speeding
McGregor seemed to make light of the situation, however, as he documented his court appearance with several posts on social media. CONOR McGregor has been ordered to appear before Blanchardstown District Court to answer a speeding charge.
He admits he would have been furious had he been the Southampton manager and termed Guardiola a disgrace for expecting teams to just roll over against his expensively assembled squad.
Guardiola said he would "never judge the way opponents play against one of my teams". All the managers want to help their players because if they play bad we'll be sacked. "It's the same as I do to beat them".
The former Barcelona and Bayern Munich boss has been given until Monday to respond to the FA.
"Nothing negative or offensive was said towards me from Pep and that's what makes him one of the best managers in world football".
City extended their lead at the top of the table to eight points over bitter rivals Manchester United thanks to Sterling's goal which sparked huge jubilation amongst the fans.
