Almeria winger Albert Crusat has joined Wigan on an initial two-year deal, the Latics have confirmed.
"Albert is someone we have been trailing for a long time and it is fantastic news that we have managed to get him," said boss Roberto Martinez.
"He will add something completely new to the squad, he has electric speed, really quick feet and has played over 150 games in La Liga.
"He is an explosive player, who understands how to affect games with his attributes, having earned his long experience in such a competitive, tactical and demanding league as La Liga.
"I am confident he can adapt quickly to the demands of the Premier League.
"I think our fans will take to him because he is a really exciting player who can bring a crowd to their feet."
The 29 year old scored 11 times in the Andalucian side's first promotion to the top flight in 2007 and has been on target 33 times in 199 games.
"It has been a crazy few days but I am really looking forward to the challenge of playing in the English league now that everything has been done," said Crusat.
"Roberto Martinez has shown great faith in me and I am determined to prove him right.
"I can't wait to meet my new team mates and get started."
