CELTIC have announced the signing of Costa Rica international Cristian Gamboa from West Bromwich Albion on a three-year deal.

The right-back arrived in Glasgow for his medical yesterday after struggling to make an impact at the Premier League club in the last two seasons.

Gamboa is Brendan Rodgers' fifth signing of the summer after Moussa Dembele, Kolo Toure, Scott Sinclair and Dorus de Vries also arrived at Parkhead. 

The 27-year-old, who has 50 caps for his country, is an attack-minded full-back who will challenge Mikael Lustig and Saidy Janko for a starting spot with the Hoops.

He moved to the Hawthorns from Norwegian side Rosenborg in a £2m deal in August 2014, but has only managed to make 17 appearances for the club since then. 

A club statement read: "Celtic are delighted to announce the signing of Cristian Gamboa from English Premier League side West Bromwich Albion on a three-year deal.

"The Costa Rican internationalist has notched up almost 50 appearances for his country and he was a star of the side that reached the 2014 World Cup quarter-finals.

"A pacey full-back with attacking instincts, the 26-year-old has spent the past two years at The Hawthorns after impressing for Norwegian side Rosenborg.

"He has also had spells at Fredrikstad and Danish outfit FC Copenhagen, having left his homeland at the age of 21."
