Vorm said that he was unaware Swansea were going to sign another goalkeeper, but welcomed the increased competition for a starting spot in the lineup.
"I didn't know they were planning to sign him, I can honestly tell you," Sky Sports News quotes Vorm as saying. "At Swansea City I can see the club is growing and there is competition for everyone, and that also applies to me.
"Fabianski was a free agent, which I understood, and he has signed for four years and the present situation is that I will be there after the summer, so I have competition.
"It may be that Swansea are already responding to my departure but then there must be [an offer]. As long as that is not the case, Fabianski and I will have to fight. I do not necessarily have to leave."
Vorm signed for Swansea in 2011 from FC Utrecht.
