Hughes' men have won their last two games to boost their European bid and Santa Cruz says everyone in the squad is focused on finishing as high up the table as possible.
"We are a good team with a big heart," Santa Cruz told Sky Sports News. "It wants to win and you can see that and that is a very important thing for everybody at the club.
"That is going to take us to the places where we want to finish."
"My goal was to score as many goals as I have right now," added Santa Cruz.
"I came with a vision to make a good impression on the team and also on myself."
