Sergio Aguero will have showdown talks with Manchester City in June regarding his future as the club have yet to inform him officially that he is wanted beyond the summer.
They hit five goals in their last two games against Monaco (Champions League) and Huddersfield (FA Cup replay), and Guardiola is pleased with the recent progress.
Centre-back Kompany, who was initially expected to play a part in the fifth-round tie against the Championship side, remained on the sidelines after an unspecified leg injury proved to be the latest frustrating setback of a nightmare couple of years on the fitness front.
"It's the best Sergio Aguero ever, the performance was incredible", said Guardiola.
Guardiola, whose side will face Middlesbrough away in the quarter-finals, would not be drawn on whether Bravo would play in Sunday's Premier League match at Sunderland.
"One thing is what the club says and another what the club tells me", Aguero said.
Guardiola said: "The performance from Claudio was wonderful".

Wagner was banned by the Football Association on Monday and fined B£6,000 for improper conduct after joining his players on the pitch to celebrate Town's late victor in the recent derby clash with Leeds.
Aguero, who is the club's top scorer with 22 goals in 30 appearances this season, has impressed since he was brought back into the team following an injury to Jesus last month.
The manager said he would wait until the season is over before taking a call on the future of several of his players, including goalkeeper Joe Hart.
The Chilean allowed a seventh-minute shot from former City youngster Harry Bunn to slip under his body in an awkward moment which also turned up the heat on Guardiola, the manager who has backed him. He is so happy, I am so happy, we are so happy. "The club can say what they want, but in June they will have to meet with me". It would be good if he wasn't playing, that's for sure.
"He scored two goals and created a lot of chances".
However, despite City having scored 10 goals in their last two games, Guardiola refused to compare City's attacking talent with his previous teams at Barcelona and Bayern Munich. We made too many easy mistakes when we had the ball and when we defended we were not aggressive enough.
