Manchester City midfielder Yaya Toure admits Robin van Persie's derby winner for Manchester United was like a "dagger in the heart". City had fought back from 2-0 down to tie up the game at 2-2 before Van Persie's injury-time free-kick.

"It was a dagger in the heart - unbelievable," said Toure.

"We thought we would win it at 2-2, but United have great experience.

"It was a fantastic game for the fans though. That is why I like the Premier League. It is the toughest league in the world."
