Manchester United midfield maestro said he felt really comfortable as he played against Chelsea at Old Trafford.
Juan Mata moved from Stamford Bridge to Old Trafford in the January transfer window and for the first time, he was lined up against his former club.
Robin van Persie's last-minute goal helped United secure a 1-1 draw against Jose Mourinho's side after Didier Drogba scored - his first Premier League goal since his return to Chelsea - in the 53rd minute of the clash.
And, Juan Mata took to his blog to reveal how his day went against Chelsea on Sunday.
“intense” day after the game, Mata wrote on his blog [One Hour Behind]: “As you can imagine, this has been a very intense day for me.
“A Sunday full of emotions because of the big game against Chelsea. Facing them for the first time was special and the match, very even in my opinion, was tense until the last minute.
“I think we did a good first half, but we weren't able to take our chances. In the second half, after Drogba’s goal they took control of the game for some time but in the last stage we pushed hard and managed to equalise.
“The truth is I felt very comfortable on the pitch, and it was nice to meet again friends and former team-mates after all these months.
“In the end, when you are on the pitch you concentrate on doing your job to help your team, and you must be absolutely focused on that.”
The 26-year-old added: “As always, the atmosphere in Old Trafford was spectacular. Your support this season is vital.”
