Sky Sports understands Celtic are closing in on the signing of United States international Juan Agudelo.
The Chivas USA man linked up with Celtic for a training stint in November as he tried to secure a move to a European club during the Major League Soccer close season.
The 20-year-old is regarded as one of the best young talents in America and has attracted the interest of a number of clubs across Europe.
Celtic are hoping to win the race for Agudelo after he impressed Neil Lennon and his coaching staff during his time on trial.
Lennon is keen to bolster his attacking options in this month's transfer window and they have now made an offer to Chivas as they look to bring the Colombian-born forward to Celtic Park.
