Amkar Perm's Brian Idowu has revealed the challenges he faced before his making his Nigeria debut.
And the wing-back has revealed his feeling of uncertainty and anxiety prior to the game.
“I wanted to check whether I can perform at a high international level [before heeding the Nigeria call]. A year ago, they [Nigeria] called,” Idowu told club website.
“Everything is new, you do not know anybody, nobody knows me, it's unclear how they will meet, what will be the situation, how I will look in training.
“A lot of good players, whose game I used to watch on TV. And then they greet me, we are partners in the team and now we train together."
Idowu who has played in 15 Russian Premier League encounters for 11th-placed Amkar Perm will hope to do enough to make Nigeria's squad to Russia 2018.
