Key Chelsea midfielder out for rest of the season

The Argentine has been struggling with the problem over the past few months, but the Blues opted against a potential operation. However, they have now changed their stance. The World Cup winner will miss the rest of the league season owing to this. Fernandez is anticipated to return in time for the Copa America. The Blues have had another dreadful campaign in the Premier League and they are currently ninth in the table with 47 points. They look set to miss out on European football for the second season running unless they can step up with regular wins. The Blues were humiliated by a 5-0 scoreline at Arsenal in midweek and they face another difficult challenge at Aston Villa . There is a high possibility that they could be on the wrong end of another thrashing unless they make a significant improvement.
