Marouane Fellaini believes Manchester United have the ability to retain the Premier League title.

The Belgian became the fifth most expensive player in United’s history when he completed a £27.5 million move from Everton on Monday evening.
And Fellaini is confident that United, who won the Premier League by 11 points last season, can see off the challenge of title rivals such as Chelsea and Manchester City again.
He told PA Sport: "It will be tough, every year is tough for the big teams but I think Manchester United has the quality to win the championship so I look forward to this. To win a trophy with Manchester United and play a lot of games, that is important."
Fellaini feels he will adjust to life at Old Trafford quickly but said he faces a battle to get into the team.
Michael Carrick and Tom Cleverley have been selected in the centre of midfield by United manager David Moyes, while Anderson, Phil Jones and Ryan Giggs offer other options there.
Fellaini added: "It is a big step for me. But I have played five years in England, I know the league and I know the players so I don't think I will have a problem with this move.
"I am playing with big players so I need to work hard for my place. I watched the game (against Liverpool) and in the second half the team played very well and had a lot of chances but couldn't score, but football is like this."
Fellaini handed in a transfer request to force through his move from Everton, for whom he had played since 2008.
And after a summer of speculation, he was pleased to resolve his future. He added: "When I started the campaign with Everton I looked forward to the transfer so in the end I was happy.
"I was a little bit nervous on Monday but in the end I have my transfer and I have won with Belgium so I am happy.”
Fellaini was speaking after Belgium’s 2-0 victory over Scotland at Hampden Park on Friday, which was watched by Moyes.
