Manchester City have been dealt a huge blow as Yaya Toure has been ruled out for the rest of the season and possibly the World Cup.The Ivorian injured his groin in the 19th minute of City’s massive 3-2 defeat to Liverpool today that has left their title hopes hanging by a thread.Manuel Pellegrini confirmed the news to BeIn Sports after the game, but failed to say whether he will now make the World Cup. Liverpool’s victory over City has opened up a seven point gap over the Etihad outfit, who have two games in hand.But the Anfield club now have fate in their own hands with just four games to play and must now be considered favourites to lift the Premier League.Liverpool can dare to dream after Phillippe Courtinho scored a late winner on 78 minutes to send Anfield into delirium after the home side had thrown away a first half two goal lead following goals from Raheem Sterling and Martin Skrtel.City showed character to strike back with goals from David Silva and Glen Johnson putting into his own net before Courtinho’s dramatic winner.
