Nicolò Zaniolo could leave Roma and join Juventus in exchange for Gonzalo Higuain plus cash, although Tottenham Hotspur offered €23m plus Toby Alderweireld.
The 20-year-old was a sensation in his debut Serie A season, having arrived from Inter as part of the Radja Nainggolan package.
He scored six goals with two assists in 36 competitive appearances, including a Champions League brace against FC Porto.
However, talks have hit problems for a new contract and new director of sport Fabio Paratici warned Roma would not go overboard with his salary.
Sportitalia and the Corriere dello Sport believe this means Zaniolo is leaning towards the exit and his favoured destination would be Juventus.
Tottenham Hotspur are also interested and the Corriere maintains the offer from the Premier League club is €23m cash plus ownership of 30-year-old Belgian defender Alderweireld.
The Giallorossi have set a €60m price-tag on Zaniolo, but Juve hope to lower that by including Higuain as part of the deal.
Higuain is a confirmed target for Roma after his disappointing loan spells at Milan and Chelsea, because his arrival would free up Edin Dzeko to join Inter.
