Pritchard, who has recently recovered from a long-term injury, is highly rated and is said to have a bright future.
The former England Under-21 international has revealed the discussion he had with Pulis before joining the Baggies.
“I spoke to Tony Pulis and coaches and was told to do my best, work hard and make an impression,” Pritchard told West Brom’s official website.
"I'm an attacking player, I like to get on the ball, make things happen and have an eye for goal. I can play on the wing or centrally - it's a dream to play in the Premier League and I hope I get that chance.”
"I don't think I'll surprise you with any others,” Goal.com quotes Hughes as saying. “It’s no secret that we have been in the market for a certain West Brom player but West Brom have been consistent in their message. We don't expect that to change."
The 22-year-old Spanish striker has put pen to paper on a new five-and-a-half-year deal with the Premier League side.
