Keane's form has reportedly caught the eye of Chelsea and he has been touted for an England call sooner rather than later, with a Three Lions squad set to be named on Sunday.
“It was the best decision I've made coming here," said Keane to the Lancashire Evening Telegraph.
“I've grown as a player and playing week in week out helps you improve so much, playing Premier League games I feel more and more comfortable."
Keane also qualifies for the Republic of the Ireland, but remains committed to England.
“I've not fully committed yet but I want to try and play for England," he said. “That's my ambition and it always has been. I just need to keep playing well and helping the team do well and hopefully one day the call will come."
