Marouane Fellaini has claimed Manchester United are not far from matching Manchester City's quality.
The Citizens beat their city rivals 3-1 at the Etihad Stadium in the final league game before the international break, leaving them eighth in the Premier League and seven points off the top four.
However, Fellaini told Sky Sports thatJose Mourinho's side are not as far away from the Premier League leaders as the table suggests.
When asked if the result had emphasised a significant gap between the two teams, he said: "I don't think so. I remember when I arrived in England it was a top four, now it is a top six, so every year it is more difficult.
"Next season we will see how it changes and in two and three years I think every year it is more difficult, the intensity is higher, so that's why the Premier League is attractive.
"Manchester City are strong, but I think they will lose. Ok, they are very good and they have good players but it's possible to beat them. We lost, but we have the second game at Old Trafford and we will see."
