Lucas was Arsenal’s fourth signing of the 2016 summer transfer window when he joined from Spanish side Deportivo La Coruna.
The striker started his career in Atletico Madrid’s youth side, before joining Rayo Vallecano’s development team and progressing into their senior squad. Having impressed in a handful of appearances for Los Vallecanos, Lucas left his homeland to play for Ukrainian side FC Karpaty Lviv.
After making over 50 appearances in the Ukrainian Premier League, Lucas went on loan to Dinamo Kiev. The forward’s next destination was Greek side PAOK, where he picked up a runners-up medal after losing to Panathinaikos in the Greek Football Cup final in 2014.
After two years in Greece, Lucas then returned to Deportivo - initially on loan - and after an encouraging debut season, he joined permanently. The striker enjoyed one of his most prolific campaigns in 2015/16, scoring 17 times in 35 games and equalling a club record held for goals in successive games.
