Swansea City striker Borja has signed for Malaga on a season-long loan.
Borja joined the Swans from Atletico Madrid in the summer of 2016, but struggled for game-time during his first campaign at the Liberty Stadium.
The 24-year-old, who is under contract with the Swans until 2020, has returned to his homeland having previously thrived in La Liga with Eibar.
Borja was a club-record £15.5 million signing for the Swans.
However, he made only 18 Premier League appearances – just four of which were starts – last season and featured twice in the cups.
His one Swans goal to date came in the 3-2 defeat at Arsenal last October.
Borja, who had to compete with the likes of Fernando Llorente and Gylfi Sigurdsson for game-time up front, came through the academy at Atletico.
He scored a highly impressive 18 goals while on loan at Eibar in 2015-16, helping them finish 14th in Spain’s top tier.
Borja made only one senior appearance for Atletico, back in 2010, but has enjoyed successful loan spells with Murcia, Huesca, Deportivo La Coruna and Real Zaragoza as well as Eibar.
He joins a Malaga side who finished 11th in La Liga last season.
They recently sold Sandro Ramirez, their leading scorer in 2016-17, to Everton.
