The tall midfielder had a difficult season with new club Manchester United, spending most of his first season at Old Trafford on the substitute’s bench, and it seemed that would continue after not being named in his country’s starting eleven against their African opponents.
Yet the 26-year-old revealed he always had faith in himself, and made an impact just six minutes after coming on in the second half to equalise for Belgium, before team mate Dries Mertens completed the comeback ten minutes from time.
I always believe and I thought that, yes, if the coach gives me the call, I can help us win this match,” Fellaini told FIFA.com.
“One thing I know is that if my team-mates put crosses in the box for me, I can score goals. And you saw it today.”
Fellaini was relieved to see the ball bounce off the back of the net, having been frustrated in front of goal by a stubborn Algerian defense.
"I'm just glad that one went in though because we were beginning to run out of time, and it was important we took one of our chances,” he said.
“In the end, I think we got what we deserved.”
Belgium sit top of Group H after their first fixture, and next face Russia in Rio de Janeiro on 22 June.
