The Spaniard left Valencia to join the Catalan giants last summer after months of speculation linking him with a move to England.
But the 29-year-old is now glad to be able to put all the confusion surrounding his career aside and focus on what he does best - scoring goals."I got used to the stories that I was going to England," Villa told The Independent. "You work just the same on the pitch but you definitely get a boost when your future is sorted out and everything calms down.
"Now I can switch off when I walk off the pitch, without the rumours that I once had to put up with.
He added, "I was lucky that when the moment came when Valencia had no choice but to sell me, Barcelona were in a position to bring me here.
"I wanted to play here and I have been lucky enough that they wanted me as part of this team and that they were prepared to pay a lot of money to make it happen."
Villa also spoke of his admiration for Tottenham Hotspur, who has impressed him with their maiden run in the Champions League this season.
"They were at a disadvantage at the start of the competition, not having played in it before, but they got a couple of great games under their belt and that levelled the playing field straight away.
"You can't call their run a surprise because you only have to look at their team sheet to see how many very good players they have."
Meanwhile, Villa and his team will face Arsenal in the last 16 of the Champions League and will be looking for a repeat of last season's 6-3 aggregate win over the Gunners in the quarter-finals.
