Swansea's record signing Borja Baston is the latest player to arrive from Spain and fail to make an impact. Liverpool and Manchester United have also had their hands burned when bringing in those who have flourished in La Liga.
It's in stark contrast to the 24-year-old Spaniard's exploits last season, where he scored 18 goals in 36 La Liga appearances while on loan at La Liga side SD Eibar, subsequently earning him a transfer to England.
Borja isn’t the first player to struggle to meet expectations following success in La Liga, and here are a few more fellow strugglers.
In 2014, he was signed on a season long loan at Manchester United, where he failed to live up to the hype surrounding him, scoring only six goals in 33 appearances.
Iago Aspas was promoted through the youth ranks at Celta Vigo, helping the Spanish club with promotion to the top tier in 2011/12.
He won an award for best forward in the Spanish Segunda, scoring 23 goals in 35 league appearances.
Fernando Morientes established himself as a first team player at Real Madrid by the end of his first season, following a transfer from Real Zaragoza in 1997.
He continued to perform well for Los Blancos before falling down the pecking order in favour of Brazilian superstar Ronaldo, academy product Raul and Liverpool transfer Michael Owen.
After a successful loan spell at Monaco, he was signed for Liverpool in 2005 by then-manager Rafa Benitez.
Morientes never managed to achieve the heights of his Madrid days, scoring eight goals in his 41 games for the club, leaving at the end of the season to return to Spain with Valencia.
