The midfielder is beginning to make an impression since his summer arrival from Salzburg.
"It is a different style of football to what I was used to in Austria," Tchoyi told the WBA website.
"The biggest difference is that the English teams are much better than the Austrian ones. I am finding it very good at West Brom and it's getting better and better every day.
"I chose West Brom because it is a team where I think we can do well, both me and the team.
"I was impressed by the way they play and I think we will do well."
