Swansea City have a deal in place with Las Palmas for Roque Mesa.
Marca says Mesa's move to South Wales will be confirmed before the weekend after Las Palmas accepted the midfielder's departure to Swansea City.
The Swans have beat Roma to the Spaniard's signature with a concise operation that only requires agreement on the final payment structure of the 13 million euro fee before he can put pen to paper.
Arriving in installments, the cash represents the highest fee Las Palmas have received for a player in its history, whilst Mesa will treble his salary once he touches down at the Liberty Stadium.
Las Palmas are set to retain a portion of the 28-year-old's future transfer fee and could earn add-ons depending on his exploits with the national team.
