The Blues ran out 6-1 winners, with four of the goals coming in the first 25 minutes. Mata created two of his team's half-dozen, including one-third of fellow Spaniard Fernando Torres' hat-trick, taking his assists tally to 13 for the season.
And Mata has announced that he enjoyed his side's performance and was happy with the overall result.
"It was a very good game for us. We enjoyed it from the first minute with Danny's goal," he told the club's official website.
"The first and second goals were very important for us, and we had more space to play our passes after that. We played very well and 6-1 is a great result.

"We had confidence from that first goal and after Fernando did a great job I am very happy for him. We are fighting to reach the third and fourth positions, which are where we are aiming.
"For the team, there are two or three very crucial weeks.
"On Wednesday we have a massive game against Newcastle, now we are one point behind them, then we have the FA Cup final, an amazing game for our supporters, so we are looking forward and hopefully we will win."
