Westwood was linked with moves to Premier League clubs during the transfer window but although grateful for the interest, he wants to play football and feels that sitting on a bench as a second choice keeper would not help his career.
"I am only 24, so I have a lot of developing to go really," said Westwood to Setanta Sports.
"As long as I keep playing well for my club, I'll be happy. And if I can make any Ireland squads then I will be delighted.
"There is always a lot of speculation in January, but there was no interest that I knew of.
"Maybe there was something behind the scenes, but nothing came out front. I don't think there was anything in place at any stage.
"If I went as a second-choice somewhere, it might hinder my progress. I want to stay in the Ireland squad and that only way to do that is by playing football."
