Union Berlin defender Leonardo Bonucci admits he could retire at the end of the season.

Bonucci left Juventus for Union Berlin last month.

He said, "I had two options to choose between Lazio and Union Berlin.

"At the end of August I chose Union Berlin. I watched the first two Bundesliga matches and I was very happy to come here for the atmosphere, the fans, the team.

"Then I spoke with the coach and I decided to accept Union's offer to experience what will perhaps be my last season.

"I played for 20 years in Italy and I think this decision is very important because at the end of my career I want to be a coach. I believe that this decision opens my mind to different things such as lifestyle and training methods, things that are completely different in Germany compared to Italy."
