West Brom boss Roy Hodgson would have no qualms starting Billy Jones in the Black Country derby against Wolves on Sunday.
Baggies regular Steven Reid is suffering from a fractured hand and Hodgson will have to consider alternative options if he is ruled out.
He believes 24-year-old Bosman signing Jones, who was Preston's Player of the Year last season, is ready for his Premier League debut.
"It will open the door for Billy," Hodgson told the club's official website.
"He is ready for the Premier League and we believe in him.
"Right from the first moment we thought we'd done the right thing bringing Billy in - and he's improved.
"Every time he's played he's had tough games.
"He played against Olympiacos and Southampton during pre-season and at Bournemouth and Everton in the Carling Cup.
"On each occasion he's done well and he's getting better and better.
"We believe in him strongly."
Hodgson considers Jones one of several new arrivals who have strengthened his squad, including Shane Long, Craig Dawson, Gareth McAuley and Zoltan Gera.
"Of our signings this year, I believe Dawson and Jones will go on to be very big players for the club," said the manager.
"Long is another one. McAuley and Gera, who are older players, will also do well.
"I'm very happy with the squad.
"We are stronger, I think, on paper than we have been.
