The manager spoke after the game about the 19-year-old's future: "Brahim knows what we want for all of our young players".
After several years with City, the player made a decision to stay with the English club at the start of this season but opportunities have proved few and far between and that could force him to seek playing time elsewhere.
Meanwhile, Legit.ng previously had reported that Manchester City star Kevin De Bruyne suffered an injury scare as the League Cup holders sealed a quarter-final spot in the Carabao Cup via a 2-0 win against Fulham on Thursday, November 1.
"We are a stronger team with Kevin than without him, but we have to live without him and we have to be there when he comes back". Asked if he was anxious about the injury, Guardiola said, "I don't know right now". He knew that at the start of the season and wanted to stay. Yesterday he came back in many things but it is what it is.
Diaz has not been a part of a Premier League matchday squad this season and has sought assurances from the Manchester City hierarchy about getting regular minutes on the pitch.
"My opinion doesn't change because he scored two goals".
"We are delighted to have him with us".
Manchester City have won seven of their last nine Premier League meetings with Southampton, drawing one and losing one. Hopefully, after the worldwide break, there'll be two or three more games and after that, he'll be back.
"Hopefully what happened in the last minutes is not serious".
