Llorente left Real Madrid 18 months ago for Atletico, which are now top of the table.
He said, "Well, one plays in white and the other in red and white… they are both huge clubs who are fighting for the same titles every year. I was at Real Madrid and now I'm at Atlético with different teammates, a different manager, at a different club. One has nothing to do with the other.
"What I can say now is that I'm really happy at Atlético, we're a very united family with a very tight squad and we show that on the pitch, the technical staff, the players, the people at the club, physios, kit people, the photographers… everybody gets along well with each other and that makes for a positive atmosphere every day.
"I'm really happy that I came to Atlético and I don't regret anything."
