And Fellaini believes United have every chance of challenging for the title this season.
He told the club's official website: "The season is long and it's only the beginning of the season.
"In the last two years, we started very well. This season, a bit less, but the season is long so let's keep going.
"In the Premier League, everything is possible so let's see. Like I said, the next game is more important than this one."
