Raheem Sterling believes it was the right time to move from Man City.
The England international joined Chelsea in a £47.5million deal in July ending his seven-year spell with Manchester City.
He won four Premier League titles, four League Cups and one FA Cup at the Etihad but was limited to only 23 Premier League starts last season.
The 27-year-old winger was struggling to find a place in Guardiola’s XI and he recently explained the reason behind his departure.
“Everyone wants to feel wanted, football is no different,” Sterling told Sky Sports.
“When you play your heart out, sacrifice some of your kids’ birthdays, and then get treated in a certain way, it’s disappointing.
“At the time I was fuming, raging, but it’s gone, it’s in the past and I can only focus on the present, which is now, here at Chelsea, and the opportunity I’ve got here to go out and showcase my talents once again.”
He added: “Misunderstandings, contracts running down. It was a shame to see how it ended in the end because I had such a great time there.
“A lot of things came into play, a lot of reasons, but I wasn’t complaining, I was ready to challenge and, as you can see, even with some of the performances I put in, you couldn’t guarantee yourself a place so it just didn’t make sense to fight a battle you can never win.”
