Former Chelsea winger Juan Cuadrado says he cannot explain why he struggled to settle down at Stamford Bridge.
After less than a year at the club, the Colombia international was loaned out to Juventus as he makes a return in the Italian Serie A after spells with Lecce, Udinese and Fiorentina.
"What went wrong? The truth is, I don't know," he is quoted as saying by Goal.
"I was always professional and I always trained very well.
"I didn't play as much as I wanted, but I was always ready.
"Moving to Juventus was the best choice for me and I hope to give my best, and give everything for this shirt.
"It's a new challenge for me. I've always been training, even if I wasn't playing, and I always train with playing in mind.
"This is a great move for me."
