"I'm so excited to see him, one of the nicest people I ever met. It was a joy for me and for all of us to work with him," Guardiola said.
"The feeling I have is he's happy there and doing an incredible job. I'm looking forward to seeing him.
"He knows absolutely everything of us, he was an incredibly important part of our success, he helped us to be who were were and who we are.
"We are delighted he will come back, especially if he is happy there. We sent a message an hour and a half ago. It was about the wine we are going to drink after the game if social distance allows!"

Pep: Walker will be judged on the pitch
Kyle Walker was spoken to by Manchester City after he breached the UK government's rules on social distancing amid the coronavirus pandemic in April.
Walker then defended himself after breaking lockdown for a second time, saying he felt he and his family were being harassed, with City opting to take no action on that occasion due to the wider context to his actions.
Guardiola acknowledged Walker's apology for his initial breach and said he will judge his players for their actions on the pitch.
"I judge my players with what happens on the pitch. He made a brave statement about what happened in this period," he said.
"The club spoke with him. I want the best for him and his family, his wife, his kids, his parents. The human being always comes first ahead of the football player.
"Kyle expressed his thoughts in a statement."
'We'll have to rotate to avoid injuries'
Guardiola made his frustration at the rapid return to action clear, with rotation to play a key role as second-placed City look to balance ambitions with players' fitness as they navigate 10 fixtures in five weeks.
Asked if he was concerned about the risk of injuries, he said: "Yes. I think we are ready to play one game but three days after (playing) another one and then four days after that (playing) another one, we are not ready.
"Not just Man City, all the teams. But that's why we have to rotate and use absolutely all the players.
"The players whose natural physical conditions are better can sustain more time."
