The Gambian born midfielder is set to start his international career with Sweden.
In July Forest boss Dougie Freedman actually had Barrow on trial at former club Bolton Wanderers. The starlet featured in a pre-season friendly against Brondby that month, as reported by The Bolton News.
Bolton were however just one of several teams trying to convince him to leave Swedish side Ostersunds FK and in the end they failed.
Instead Barrow joined Swansea City and has gone on to feature for the club nine times this season, recently signing a four year extension to his current deal at the club.
Now Freedman does have his man and Barrow made his debut for the club as a substitute against Rotherham last night.
His career is certainly an interesting one. He has already played for six clubs in his career and the Gambian seemingly arrived from nowhere to make an impact at Swansea.
Then there is his international future.
Born in Gambia but living much of his life in Sweden, he is eligible for both. So who will he play for?
After months of deliberating it seems we now know.
As reported by Fotbollskanalen Sweden under-21 coach Haken Ericsson has spoken to Barrow about joining up with the Swedish set-up and it looks like he will be turning his back on his country of birth:
"We had a good meeting and he is positive. We have until Friday [March 20] when we will release our next squad list, so really, I will not comment so much more than that. I do not want to precede the process."
Of course this is an important step in his development but the Swansea owned player has not yet set anything in stone. Playing for the Sweden under-21s will not effectively rule out a future playing for the Gambian national team. But at this moment in time, playing for the Swedish under-21s would be far more beneficiary to Barrow than making the step to full international football with Gambia.
