West Brom boss Tony Pulis has declared their deal for Al Ahly defender Ahmed Hegazy as "perfect".
Hegazi joins on loan from Cairo's Al Ahly with an option to buy at the end of the season.
"It's a magnificent deal for us as a football club and it gives us the opportunity to see if he can adapt to the Premier League," he said.
"We have got it all tied in with the club that if we like him we can take him.
"I don't want to put too much pressure on the lad. We've been looking at him for a long time and we've managed to get the deal we wanted."
Pulis said signing the Egyptian on a permanent deal right away would have presented too much of a risk.
"We didn't want to take the chance of signing him on a permanent deal because you just don't know the character and the understanding of English football and English tradition and the English values of life.
"So I think we've got the perfect deal and you don't get them too often," he added.
