West Brom have confirmed the club-record transfer of Venezuela international striker Salomon Rondon from Russian club Zenit St Petersburg for a fee of £12m.
Baggies boss Tony Pulis has called on Baggies fans to give Rondon time to settle.
"He's got a fantastic goalscoring record in some of the top leagues in Europe and for his country," said Pulis. "He's 25 years of age and still to fulfil his full potential.
"We hope he hits the ground running of course but understand it might take him time to settle. I'm sure our fans will help him and get behind him.
"But we feel with age on his side and the prices English clubs are asking for their players, it's a deal worth doing. "
The 25-year-old, who has signed a four-year deal at the Hawthorns, said: "I am very happy to be at West Brom. This is a new opportunity in my career and I can't wait to play."
