The 29-year-old Manchester United midfielder thinks his club should improve after his team draws a match against the West Brom on Saturday.
This season the Manchester United side drew eight of their matches at Old Trafford and in total 11 games so far.
After their last match against West Brom where they unable to score one single goal against their counterpart at their home soil, the Manchester United side still finds themselves at the fifth spot on the table.
Earlier in this season, the Red Devils side has also been held the home goalless draw against Hull and Burnley, and the 1-1 draw against Bournemouth, West Ham, and Stoke.
Fellaini said: "It's disappointing, everyone is disappointed,"
"We've lost a lot of points like that, but that's football and we have to keep fighting. We have to improve on that.
"When you play away, the other team tries to attack. It's not easy to play at Old Trafford, they came to take a point or win with a counter-attack. But we have to find a solution to win the game."
While under the special one the Manchester United side is 19 matches unbeaten in the EPL but still their recent draws won’t help them out to secure their place in the Champions league.
In their next match, the Manchester United side will take down the Everton side.
He added: "There are 10 games [left in the league for United], 30 points so we have to keep going,"
"There are a lot of big games coming and we have to be ready. There are six points available next week and I hope we can take them.
"It [the match against Everton] will be a tough game. They're a tough team but every game will be difficult and we have to fight to the end."
