If the immediate present is looking rather rosy for City, then the future is in safe hands too with young talents like Celina waiting in the wings.
The 20-year-old has long been tipped as one of the brightest talents in City’s renowned academy system and caught the eye in a number of brief cameos last season, making his Premier League debut in City’s 3-1 home defeat to Leicester and setting up a consolation goal for Sergio Aguero with a sublime cross.
However, due to the wealth of attacking talent at Guardiola’s disposal in his first season at the Etihad, Celina was farmed out on loan to Dutch side FC Twente in the summer where he has shone alongside fellow City starlets Enes Unal and Yaw Yeboah.
Though that’s not to say the Kosovan international has no immediate future under the former Barcelona boss, having inked a new four-year contract in May and impressing when coming off the bench against Bayern Munich in pre-season, Guardiola’s first official game in charge.
And Celina says he has already learned a huge amount from arguably the greatest tactician in world football, despite spending just a few weeks in his company.
"Pre-season with Guardiola was an amazing experience for me," Celina told Sky Sports.
"I learned a lot of stuff I didn't know before. I was really surprised by how much he spoke to the young players.
“He told me he knows I've got a lot of skills but I don't always need to show it. Sometimes it's better to play a simple pass, to use your ability in a better way."
Together, Celina, Yeboah and Unal have combined to score 14 goals in highly impressive stints in the Eredivisie, inspiring a Twente side who struggled badly last season to the dizzying heights of the top six.
