Sergio Aguero starts but John Stones is on the bench for Manchester City in this evening's important Premier League clash against West Bromwich Albion at the Etihad Stadium.
Club chairman Khaldoon Al Mubarak brought Txiki Begiristain and Ferran Soriano to City in 2012, two of the main figures Guardiola worked with during his time at Barcelona.
First-team players are set to spend some time at the club's Etihad Academy next week after a busy season and will be taking part in some commercial activity ahead of the club's summer tour to the United States.
Guardiola is in the process of shaping his squad for next season, and while Zabaleta's future has been decided, those of City's six other out-of-contract players remain in the balance.
"Gabriel was incredible, but the key player up front was Sergio (Aguero)", Guardiola added.
Manchester City supporters said an emotional farewell to long-serving defender Pablo Zabaleta in Tuesday's final home game of a trophy-less season - a 3-1 win over West Brom. It's my first year here but when I saw what I saw tonight I see what an impact he has had for this club.
The Argentina right-back, 32, is leaving City after nine years at the club.

"Of course, in every country the weather conditions are different, the referees, it can be more physical".
The victory lifted them above Liverpool to third in the Premier League with just Sunday's trip to Watford to come. I'm happy it's in our hands to finish third.
"If you link him to West Ham, which seems to be the case at present, he'd be absolutely flawless", said Brooking.
At Manchester, it was pretty much a flawless night for Manchester City.
Zabaleta was quoted by ESPN saying: "When I first came to Manchester I felt like when I was in Barcelona at Espanyol, we were not the main club in the city - we can't say the same thing now".
"The team, the players, the manager need to be in the Champions League, in the greatest competition in the world next season".
"But the fact I have been here from day one is something that has made me very proud".
