The meeting comes just hours after Manchester City unveiled their new £27million signing Gabriel Jesus.
The Argentina international and Guardiola reportedly had a falling out earlier in the season when the City boss dropped the striker from his squad for their Champions League match against Barcelona.

Guardiola has repeatedly spoken out about wanting more from Aguero this season despite scoring 18 goals in all competitions.
And with Jesus' arrival speculation has started to build about what that will mean for Aguero's career at City.
Jesus is eligible to make his debut against Tottenham tomorrow (5.30pm) and City's sporting director Txiki Begiristain has already hailed the 19-year-old as the future of the club.

"He has the potential to become one of the best attacking players in the game and we look forward to watching him develop further here in Manchester,' said Begiristain.
"I think with Pep Guardiola as manager and the squad we already have here, Jesus has the perfect platform to reach his full potential."
