Celtic are exploring a deal for West Bromwich Albion right-back Cristian Gamboa before the close of the transfer window.
The Parkhead club want two new faces before midnight on Wednesday, with a midfielder and right-back priority positions.
Hopes of securing a loan deal for Liverpool defender Andre Wisdom have been frustrated by the Anfield club’s desire for a transfer fee.
And that has prompted Parkhead boss Brendan Rodgers to run background checks on pacey 26-year-old Costa Rica international Gamboa as an alternative.
