Anderlecht player-manager Vincent Kompany believes Liverpool and Manchester City are a class above the rest of the Premier League.

Former City captain Kompany believes it could be years before the rest of the top six - Manchester United, Arsenal, Chelsea and Tottenham - catch up.

"My opinion is that, at the moment, it's very difficult for the other clubs to compete because Liverpool and City are well-oiled machines," said Kompany, as quoted by the Mirror.

"Each player knows what to do. I think these guys are there to stay and the other ones will have to improve fast or otherwise that gap will remain.

"It seems that even if they don't have a great day, it's still a comfortable game and there aren't many teams in recent history who've been able to have comfortable games in the Premier League.

"These two teams have been so good at nullifying the danger from the other teams, I don't see the other teams being able to do that yet.

"City and Liverpool have a huge volume of games which you can expect them to win and that gives them a massive advantage when it comes to overall league tables."
