Supporters taunted rivals after Wembley victory...

Gloating Chelsea supporters reportedly hacked into Manchester United's phone system to taunt their rivals about their FA Cup and Premier League double.

According to the Daily Mirror, callers who contacted United on Saturday were greeted with "We are the champions" instead of the usual message saying the club would open for business again on Monday.

A United spokesman confirmed the incident last night and stated an investigation was underway.

"It did happen, but we got to it quite quickly. An investigation is underway and if we find the culprits we will decide where we go from there," the spokesman told the Mirror.

The Blues finished one point ahead of United at the top of the league table and beat Portsmouth 1-0 in the weekend showpiece.
