"It's a key victory to try to climb the table and go to Germany full of confidence," Mata wrote on club's official website. "This victory gives us a lot of energy for our game in Munich on Wednesday.
"I'll be supporting from home, in front of the TV, aware that the Allianz Arena is one of the toughest stadiums in Europe... but also aware that we are Manchester United and I'm sure we can make it through!"
Mata is delighted to be finding his feet at his new club and says he is enjoying his football again after struggles for United and himself personally this season.
"I scored and enjoyed on the pitch again," he wrote. "I wish the streak goes on until the end of the season.
"The truth is, after a game like Saturday's, I realise once again how nice football can be, and how much you enjoy the few days following a victory and a good performance."
