Juan Mata admits Manchester United want revenge on Chelsea ahead of their FA Cup quarterfinal.
Chelsea thrashed United 4-0 earlier this season at Stamford Bridge.
"It's going to be another special game for me," Mata told United's official website.
"This is, without a doubt, one of the most complicated ties we could have.
"But we will go there with the big motivation of earning a ticket to Wembley and forget the bad taste of our last visit to Stamford Bridge."
