Former Celtic keeper Artur Boruc has revealed it was too easy to retain his place in the Hoops side. The 30-year-old spent five seasons in Glasgow after joining Celtic from Legia Warsaw in 2005 and made 163 appearances for the Bhoys, keeping 79 clean sheets.
The Poland international is now with Fiorentina but reflected on how his time at Parkhead was too comfortable.
"In Glasgow, I became a bit lazy because they all loved me no matter how I played," he told Polish television. "I loved Glasgow, however, at some point in life you must change.
"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."
