The striker left Chelsea on deadline day Monday to join Bayern Munich in a loan-to-buy arrangement.
He told Tuttosport: Football is full of cycles. Sometimes things don't go as they should, and that's part of the game.
“I respect coach Maresca, I learned a lot from him, he has his own ideas and style. I just needed something different at this stage of my career. I have no regrets, just gratitude for my time at Chelsea.”
On those attempts from Chelsea to initially block the move, Jackson also stated: "Honestly, my advisors and I were very confident. I never doubted that I would sign with Bayern, so I took the situation philosophically.
“I'm in good health, as are my loved ones, and I'm lucky to be a professional footballer. Nothing else matters.”
