Sassuolo chief Giovanni Carnevali has warned Roma they face competition for Davide Frattesi.

The former Roma midfielder is being linked with a return to the Giallorossi.

But Carnevali told La Gazzetta dello Sport: “We are on good terms with Roma and we have valorised several players coming from their academy.

“It's going to be a long month, we have some requests, but our desire is to keep the team competitive.

“We are unwilling to sell our players in the current [January] transfer window, but we'll see which opportunities we'll have. We also have some requests for other players, but we mostly focus on new signings."
