"I am very happy because we got an agreement with the people from the club," Santa Cruz told Radio Rovers.
"I was also trying to push it so we could get the deal done because people were talking too much about situations which weren't really there.
"So I think that starting this week we can have an easy week now in training, and just enjoy and concentrate on each game.
"I think it is great news for the fans, but also for the players, the gaffer and for me. It wasn't a good thing to get phone calls every day asking me what is happening.
"So for me it is very important that it is all done and now I can just focus now on Blackburn and football, I'm 100% a Blackburn player and I will keep working hard."
