According to well-known reporter Di Mazio, Roma hopes to introduce Echeviri by loan + buyout, but Manchester City is only willing to rent out simply.
Di Mazio wrote on his official website: "The negotiations between Roma and Fabio Silva are difficult. First of all, Echeviri has problems with terms: Manchester City intends to let the player leave only on loan."
"Echeviri is very attractive to Roma. They are willing to let the player occupy the second non-EU player, but they hope to add a buyout option to the contract."
"As for Fabio Silva, Wolves intend to sell the player permanently, but Roma cannot afford such a price at present."
