Mata became only the fourth player to retain the trophy, adding his name to a list containing John Hollins, Ray Wilkins and Frank Lampard, and the 25-year-old was understandably delighted.
"I feel so happy," he said. "It's my second season here and winning the trophy two years in a row is amazing for me. I just want to say thank you to all the supporters and all my team-mates."
He went on to pay tribute to our supporters for their backing in last night's Europa League final win over Benfica in Amsterdam.
"Every final, like last season in the Champions League, we felt all the people from Chelsea with us,' he explained. 'We did it for them, we scored in the last minute, the best time to score, and we were really happy for them because they've been behind us all season."
Mata was presented with the Player of the Year award by club captain John Terry, who felt the playmaker was a worthy winner.
"He's been phenomenal," said Terry. "It's not just his goalscoring, it's his assists as well. He's fantastic, he brings so much to the team. He's a magician, he has a great first touch and fantastic vision."
