Ecuador international Jefferson Montero arrived at The Hawthorns from Swansea City on deadline day of the January 2019 window with an impressive CV to hand.
The 29-year-old has won over 60 caps for his country, scoring 10 goals, and was part of the squad that went to the 2014 World Cup in Brazil.
He began his career in his native country, first playing professionally at Emelec and impressing during spells at Independiente del Valle and Mexican side Dorados de Sinaloa.
Montero then signed for Spanish side Villarreal in 2009, where he made 15 appearances, before temporary switches to Levante and Real Betis ahead of a move back to Mexico with top-flight team Monarcas Morelia in 2012.
His two years in Liga MX were the most prolific of his career so far as he netted 10 times in just over 60 showings, prompting a move to Swansea City ahead of the 2014/15 season.
Jefferson's time in South Wales has seen him play a total 84 games across the Premier League, Sky Bet Championship and various cup competitions, netting twice and claiming 13 assists at the Liberty Stadium.
The left winger has been used mainly as an impact player over the first-half of this season, coming on 12 times and having a hand in three goals for the Swans.
