Celtic completed its signing of Costa Rica international Cristian Gamboa from West Bromwich Albion on Tuesday.

The marauding right-back joined the Baggies after impressing at the 2014 World Cup, but now moves north on a three-year contract in Parkhead.

Gamboa becomes new manager Brendan Rodgers' fifth summer signing, following Moussa Dembele, Kolo Toure, Scott Sinclair, and Dorus De Vries, and joins an outfit that has begun the domestic campaign with three straight wins.

Celtic's next match is the first installment of this season's Old Firm derbies with Rangers on Sept. 10.
