Boruc left Celtic for Fiorentina over the summer, but he is struggling to become the number one for the Viola.
“In Glasgow, I became a bit lazy because they all loved me no matter how I played,” he claimed on Polish television.
“I loved Glasgow, however, at some point in life you must change.
“I know that at Fiorentina I have to work hard because, compared to Celtic I have to earn my space. Now is a different situation that involves more work for me.
“I came to Fiorentina because I wanted to go to play in a better championship. I love Italy, I feel good here and I have also begun to speak Italian.
“Now in Fiorentina I must make everyone understand my worth. I’m very ambitious and optimistic.”
