City travels to Brighton and Hove Albion on Wednesday (AEST) for the penultimate game of its triumphant Premier League campaign, before lifting the trophy in front of their fans against Everton on Monday.

Sergio Aguero will hope to bid farewell to the Etihad Stadium faithful at the weekend in his last home game before departing in the close season, although the injury woes that have ruined the Argentina striker's final campaign in Manchester have returned and he will not travel to the Amex Stadium.

"He has niggles. He's a little bit disturbed in his leg, his adductor," Guardiola said.

"He felt something before the Newcastle game. He's still not fit. Hopefully he’ll be ready to play against Everton."

Sentiment might enter Guardiola's thinking on the final weekend of the domestic season, but he will be all business in Porto on May 29, when City take on Chelsea in a bid for their first European trophy for 51 years.

"I would say I would be cold. I have to take a decision which is the best to win that game," he said.

"If Sergio is fit, he is going to help us, that is for sure. If he is going to help us score goals, he is going to play, but it's the final of the Champions League.

"I have to take the decision that gives us the best chance of winning that game."

For forwards like Aguero or Ferran Torres – who staked his claim with an excellent hat-trick in the 4-3 win at Newcastle United – any hopes of selection at Estadio do Dragao might be forlorn, given City's progress through the knockout rounds relied largely upon deploying the likes of Kevin De Bruyne, Phil Foden, Bernardo Silva and Ilkay Gundogan in a striker-less formation.

However, after the victory at St James' Park, Guardiola intriguingly said he has "two options" for the final and on Monday he stated selection was more up in the air than in his 2009 and 2011 Champions League triumphs with Barcelona.

"Always it was difficult but always I remember the first XI of Barcelona was clear," he said.

"Here we rotate a lot and everybody can play, so still right now I am not clear the way we are going to play and with who we are going to play, so that’s why I have to take a look these 10, 11 days. After, we have to take the decision.

"This is the toughest moment. That is why the relationship between the players and the manager has to have a little bit of distance.

"You cannot have that close a relationship because you have to take decisions that take part in their careers and sometimes I am unfair to them, but it is what it is. I don't have another solution."

Nevertheless, none of this has stopped plenty of training ground pleasantries over recent days, with Guardiola knowing this is not simply as a result of spirits riding high after being crowned champions last week.

"They listen a little bit more. It's a serious point, they’re not stupid," he chuckled. "They want to play, so they are nicer to me.

"Then I will make a selection and they will be who they are normally: grumpy, upset with me. That's normal."
