CRISTIAN GAMBOA got one over his Celtic team-mates Stuart Armstrong and Callum McGregor at Hampden last week.
The attacking right-back helped Costa Rica to a 1-0 victory in the friendly as Alex McLeish made his return as Scotland manager.
The Hoops double-act had to wait until the 58th minute before they got the nod to try to rectify the situation with the Central Americans already leading from an early strike.
Gamboa said: “I was joking with all the Scotland boys before the game so it will be nice going back to Lennoxtown having won.
“I think Scotland did well, certainly in the second-half, and it was good preparation for us for the World Cup.”
His nation’s win in Glasgow was one of the rare occasions for Gamboa to smile this season.
The 28-year-old defender, who cost £1.2million from West Brom in August 2016, has only made three appearances for the champions
Gamboa is eyeing a place in his country’s World Cup Finals squad for Russia in the summer and is going into overtime to achieve his target.
He said: “I have brought a personal trainer over from Spain to help me. I need to think about myself now.
“I have been doing a lot of extra in the gym. It is difficult for me because they are winning every weekend.
“I have been working with this guy for the last two weeks and I will keep working with him until the end of the season.
“The quality of the training at Celtic every day is very good, but you still need extra and you need to find this by yourself.
“For now, I just want to concentrate on getting to the World Cup and then see what happens.”
Gamboa, who still has a year to run on his Hoops contract, added: “I have spoken to the manager and he understands the situation. I also understand his situation.
“He has Mikael Lustig and know Jack Hendry, who can also play right-back.
“I need to take care of myself. If they need me, then I have to be ready.”
