Ake chose to leave Chelsea in a permanent deal this summer.
He told the London Evening Standard: “I have no regrets, no way. I am still 100 per cent happy with my decision.
“It is still early in the season. We didn’t start the season well, but the quality of our football is coming back, we are scoring good goals. The defending is getting better too.
“It’s just about picking up more points and we will do that with the quality we have in the squad.”
Ake added: “At the end of the season I just felt that the time had come. Chelsea were disappointed and wanted to keep me, but they understood as well. They didn’t want to stop me from fulfilling my dreams.”
