The Belgium international has been a reliable figure for the Red Devils under Jose Mourinho and he notched up an assist to help Manchester United claim a 2-1 win at Watford in the Premier League on Saturday evening.
Fellaini is known for being something of a controversial figure but Mourinho has always talked up the importance of the midfielder to his team.
And Ferdinand feels that the 30-year-old deserves credit for the role he has played in the Manchester United team since Mourinho’s appointment at Old Trafford.
Speaking to BT Sport after Saturday’s game, Ferdinand said: “You have to understand why Jose’s got him in the team.
“He’s not pretty to look at but he’s very effective in what he does. Many of the games he plays in he has an effect on the result because he is so dominant in terms of his figure and physicality.
“He’s demanding of himself, I was at the training ground with him for a year and he’s a great professional. When the chips are down he doesn’t shy away.
“He will have seen the media and some of the fans who are with and against him. He says ‘listen I want to stay and work hard and be a Manchester United player’ and I think you have to respect that.”
Manchester United will now switch their focus towards Champions League affairs and their home clash against Young Boys on Wednesday night.
The Red Devils are looking to be one of the main challengers for the Premier League title this season after they finished second and without a trophy in the top flight last term.
Manchester United have not won the Premier League title since their famous final triumph under Sir Alex Ferguson back in 2013.
