Swansea City have agreed the signing of Atletico Madrid striker Borja Baston in a club record deal worth €18m (£15.3m, $20m), IBTimes UK understands. The deal is now only pending the medical of the Spaniard after the Wales side ironed out the last terms of the agreement with both the La Liga side and the player following the sale of Andre Ayew to West Ham.

Baston is expected to travel to Swansea on Tuesday evening in order to undergo his medical at the Liberty Stadium on Wednesday before signing a four-year deal with the Premier League side.

Swansea also completed the signing of former Spanish international Fernando Llorente from Sevilla last week. However, manager Francesco Guidolin was still desperately looking to sign at least another number nine after having seen Eder, Alberto Paloschi, Bafetimbi Gomis and new West Ham record signing Ayew leaving the Liberty Stadium during the current transfer window.

Baston becomes the Swansea record signing after the Wales side have agreed to pay Atletico Madrid around £15.3m for his transfer, beating the £12m they paid Vitesse Arnhem for Wilfried Bony in 2013.

The Spaniard has also received offers from Wolverhampton and Malaga during the current transfer window but has opted to move instead to the Premier League side after agreeing a four-year deal.

The 23-year-old striker used to be considered as the next big thing to emerge from the Atletico academy since the emergence of Fernando Torres. However, a serious knee injury during his first-team debut with Los Colchoneros in 2010 hampered his breakthrough.

The Spaniard managed to recover from the disappointment and has proven his worth in successive loan spells at Murcia, Huesca, Deportivo de La Coruna, Zaragoza and Eibar. At the Basque side he proved to be one of the sensations of the 2016-2017 campaign, scoring 18 goals in 36 La Liga games.

Many in Spain asked Vicente Del Bosque to include him in the squad for the Euro 2016 while some Atletico fans expected Diego Simeone to give him a chance with the first-team in the coming season. However, with new signing Kevin Gameiro, Antoine Griezmann, Angel Correa and Fernando Torres also in the attacking ranks the player has opted to enjoy a new experience in the Premier League.
