The Belgian midfielder came on at half-time and immediately changed the game with what was his first goal in a Manchester United shirt.
After having such a poor first season with the club, Fellaini wants to push on and make his goal the first of many.
“It was my first goal this season and for Manchester United as well, so it was good for me,” said Fellaini.
“But the result was a disappointment because our two next games are very difficult games. For the confidence, it is not so good.”
Scoring his first goal was a big step for Fellaini and will really boost his confidence: “It was a good feeling, I have waited for a long time for this moment and now I have scored, so I hope to score some more goals this season.”
“It was very difficult but I work hard every day and I know that when I am 100 per cent fit then I can be dangerous.
“Football is like this, sometimes you have bad moments and that was one. But I am ready for the challenge and to play every game. I am happy here and the manager has shown trust in me. Every day in training, I work hard and after that the manager makes a decision.”
United’s boss showed faith in Fellaini given that there were other options on the bench and after the game he explained what Van Gaal had asked him to do: “I have to put pressure [on the opposition] and go into the box. I did that and I scored, so it was good for me and the team.”
Fellaini was written off by plenty of fans but under Van Gaal, he’s been given an opportunity and took it with both hands yesterday against West Brom.
Will Fellaini come good on his £27m pricetag? Time will tell but if he is played in a more advanced position, he might start to show the sorts of performances that made him such a dangerous player at Everton.
