The Argentine midfielder joined the Baggies on a two-year deal from Ukrainian outfit Metalist Kharkiv in the summer, despite having doubts over whether a move to England would suit him.
He has yet to make a Premier League start, but Blanco has insisted that he is enjoying life at The Hawthorns as he adapts to the change in playing styles.
"It wasn't easy leaving Metalist, the negotiations for leaving were very tough, but in the last week of the transfer window interest appeared from English teams," he told reporters.
"When I found out about this chance, to be honest, I was a little nervous because it's a physical style and that isn't one of my strengths. But now I think that I made a very good decision and have taken a very important step forward in my career.
"In England, football is played very fast, some players look heavy but they are very fast and everything is dynamic. I have been surprised that everything is so professional in England. The smallest teams look like the biggest teams from any other country."
Blanco, 26, was part of the West Brom side which was knocked out of the League Cup by Bournemouth on Tuesday.
