Rangel admitted he was disappointed that a loan move to Fulham failed to come off.
But he insisted: "I won't let it affect my performances.
"Every player wants to play at the highest level and in this country that's the Premier League. Jason Scotland and Jordi Gomez had to leave Swansea to play in the Premier League. But I want to get there with this club.
"I'm not thinking about my future. I'm just focusing on this season. I'm a Swansea player and I'm 100 per cent committed to the club.
"The contract situation isn't on my mind. I'll look at my future at the end of the season. I'll sort things out in the summer. You never know what is going to happen.
"My dream is to get to the Premier League with Swansea, that's my dream.
"Swansea gave me the chance to play in British football and to become a professional footballer.
"It's the club I play for and a club I love. That's why winning promotion to the Premier League with them would mean so much."
