Goncalo Guedes has demanded a transfer from Valencia.
The Portugal striker spoke last week of being unsure over his future at the Mestalla.
Calciomercato.it says Guedes has now asked for a transfer amid interest from Roma.
The striker is keen on the move and the chance to work with Roma coach Jose Mourinho.
The problem is the €40m asking price, though Roma could be willing to include a player in their proposal to bring down the cash component.
