Bologna, Celtic, Bayern Munich and Lyon are all waiting for a decision from Hearts full-back Aaron Hickey.
According to Sky Sport Italia, Bologna had presented their proposal months ago, even giving him a guided tour of the training facilities.
However, there is extremely strong competition for the right-back, who turned 18 in June.
He can also play in the centre of defence and as a left-back.
Celtic and Bayern Munich were already in the running, while now Champions League semi-finalists Lyon have stepped forward with an approach.
