Manchester United squandered a 2 - 0 lead at Old Trafford as Chelsea came back to draw in the FA Cup.

After the agony of losing to Real Madrid on Tuesday, United started with the bit between their teeth, as Chicharito Hernandez' looping header giving them a deserved lead after four minutes.

Six minutes later it was two as Wayne Rooney's inswinging free-kicked curled over a mass of bodies in the penalty area and all the way into the net to leave the Reds well in control.

But Chelsea fought back in the second half. Hazard pulled one back with a powerful strike on the hour mark.

And 20 minutes from time, Ramires earned a replay as finished off a counter-attack.
