The City head coach pushed Redmond in the chest and harangued the 23-year-old as he tried to walk off the pitch moments after Raheem Sterling's 95th-minute victor.
Redmond has also said that Guardiola's words were encouraging, but Roberts has taken a different point of view and believes the Manchester City boss has no business telling an opposition footballer how to play.
Guardiola expects to find out on Friday if he faces FA action over the confrontation. He has not been charged with misconduct at this stage.

He added: "I told him I was doing what my manager had asked me to do in the game". "I said to Nathan: 'You are a good player and you have to attack'".
"Losing the game the way we did in the last kick of the game after working so hard for 90+ minutes, I was very disappointed".
"I said [to the referee] I apologise because i couldn't control it, I was so happy like all the fans and players". I have to do that but I could not. "Hopefully, I will improve", Guardiola said, as reported by the Mail Online. However, Redmond banished the reports along with claiming it as false news.More news: Missing Florida teen has 'emotional reunion' with family
"[I told him] how good a player he is", Guardiola said. "I admire him as a football player and I say thank you for his comments". I don't know why we make press conferences.
"I explained what happened".
"If they want to listen to me, I will do it". Redmond issued a statement on Twitter in response to growing media speculation, confirming "nothing negative or offensive was said". "It's not a problem".More news: Nigeria draw Argentina for 5th time
Last seasons, Guardiola's Manchester City side drew at the hands of Redmond and co, where the winger outshone the entire team in October 2016. All the managers want to help their players because if they play bad we'll be sacked.
However, the matchup turned out to be far from a straightforward one for Guardiola's men, with Oriol Romeu's equaliser 15 minutes from time having thrown a spanner in the works for the Premier League table-toppers, following Kevin De Bruyne's opener in the 47th-minute. "It does no favours to the sports journalists in the game that I like, happily work with and genuinely respect". "Today he could not attack because he defends all the time". I was friends with Mauricio in Barcelona. "It's the same as I do to beat them".More news: Police in Potsdam, Germany evacuate Christmas market, investigate suspicious object
