Anil Murthy, Valencia president, is in Barcelona to negotiate the final details of Rodrigo's move to Camp Nou, per Superdeporte.
The Valencia chief has headed to the Catalan capital to seal the loan switch. Barcelona want the deal to be sewn up quickly so if something happens they can go elsewhere.
These are key hours, where both clubs will settle their tug-of-war over the terms. Valencia want an obligatory option to buy in there. Barcelona don't, and could include a player going the other way.
