Guardiola's behaviour appeared to be aggressive but he claimed afterwards he was merely praising Redmond's attacking qualities - something the once-capped England global corroborated in a statement issued on Thursday to refute allegations made by The Sun newspaper that the City boss directed foul and abusive language towards him.
Redmond went public on the matter after an article in The Sun newspaper accused Guardiola of aiming foul and abusive language towards him and insisted the Catalan's "intense and aggressive" approach was wholly well-intentioned.
In the immediate aftermath of Premier League leaders City snatching the points through Raheem Sterling's 96th-minute victor, Guardiola approached Redmond on the field and gesticulated in an animated fashion. "I did it in Munich, with my old player (Joshua) Kimmich, I did the same in Dortmund and had regret there after the game and the same now". "Hopefully I can improve".
Speaking after the match, Guardiola said he told Redmond "how good a player he is". But they didn't want to play, they were time-wasting from the ninth minute.
But having reviewed footage of the incident, the FA have sought Guardiola's version of events. I didn't know him last season, I realised how good he is.
"That is not your job it's his manager and what you want them to do just let them open up so you can score a lot?"
Redmond took to Twitter on Thursday night to brush off the conversation as "positive and complimentary" although Guardiola admitted on Friday he regrets his actions.
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: "I have played against millions of managers and the different ways they play".
Guardiola said he would "never judge the way opponents play against one of my teams".
'I told him I was doing what my manager had asked.
City's win over Southampton came courtesy of a 96th minute goal from Sterling, the third time in eight days the England striker had scored a late decider.
