Celta Vigo have allowed Claudio Beauvue to join Leganes as reports claim €25m for Emre Mor is agreed.
Beauvue had been linked with a summer exit for some time and his move to Leganes will now be completed on Tuesday after he arrived in Madrid for a medical.
The Guadeloupe international will arrive at Los Pepineros on a one-year loan deal, having failed to find regular football with Celta following his move from Olympique Lyonnais in January 2016.
Despite interest from French clubs, Beauvue remained keen to stay in Spain.
His departure opens up the arrival of Emre Mor from Borussia Dortmund and it is understood that a fee has now been agreed by Celta officials.
€25m is the said figure that Juan Carlos Unzue is willing to pay for the 20-year-old, who is said to have jetted into the Galician city on Tuesday morning.
The winger will sign a five-year deal at the Balaidos and will bolster the club’s attacking options, alongside Maxi Gomez, Iago Aspas and Pione Sisto.
Celta have had a slow start to the new La Liga season, having lost 3-2 to Real Sociedad on the opening day of the season and losing again at the weekend to Quique Setien’s Real Betis.
