Mata was linked with the likes of Arsenal, Tottenham, Manchester United and Paris Saint-Germain over the summer.
But the former Valencia man insists that he is happy to stay at Chelsea.
“I think it’s normal in every transfer window that there are lots of rumours but I’m happy here,” Mata told Chelsea TV.
“It’s been a very, very good two seasons for me here, maybe the best of my career, and what I want this season is the same.
“I’m looking forward to achieving as many trophies as we did the last two seasons (Champions League and FA Cup 2012, Europa League 2013) and hopefully this is going to be a good season for us again.
“Has it been hard for me to focus on my football with all the speculation? For me it’s not, if you have things clear in your mind and have belief in yourself. My only aim is to play here, grow as a player and do as good a season as the last two which were amazing for me.
“These two seasons have flown by, but to me this is good because when you are enjoying things and you are happy, time goes quicker.”
