The Turkish powerhouse have long been linked with a move for the former Barcelona star and their coach believes he could take his side "to the next level"
The Turkish side have long been linked with a move for the Brazil international and Bilic has now confirmed that they are eager to sign the 33-year-old in order to help the club to progress "to the next level."
"I would love to have Ronaldinho in my squad," the former Croatia boss told reporters.
"He might be a little older now, but I think that he still has at least two good years in him. Even at his age, he would contribute a lot to Besiktas and could help us to the next level.
"Let's not talk about it too much, though, at this stage."
Ronaldinho joined Mineiro from Flamengo in the summer of 2012 and guided them to Copa Libertadores glory in his first season at the club.
