Graham Dorrans, Zoltan Gera, Markus Rosenberg, Goran Popov, Diego Lugano and Steven Reid have all been battling for starts this season, but the Scottish coach believes that they will be desperate to prove themselves at The Hawthorns.
"They are all Premier League players, who will want to play at this level," the 50-year-old told reporters. "They will want to play here for the Albion - they show me that every day.
"I don't expect anyone else to want to go out on loan."
The Baggies are currently 12th in the Premier League.
