The Midlands outfit are reported to have received a bid from fellow Championship side Hull City for forward Sylvan Ebanks-Blake, an offer which Saunders admitted may need to be considered.
And, despite his eagerness to keep his squad stable with top-flight clubs also looming, the Welshman conceded that every player has a price.

He told reporters: "We've had quite a big bid for Sylvan and there will be a point where you have to say 'yes' because everyone has his price.
"I asked the chairman if we could keep him because you can't replace strikers who are scoring unless you have £3 million or £4 million.
"We've turned the verbal offer down and hopefully they don't come back.
"If a club makes a ridiculous offer, I've got a list of replacements but they might not come or they might have gone elsewhere.
"It's a limited market. There are lots of waifs and strays. I'd rather the window shut.
"We've had phone calls about four or five other players, and from Premier League clubs as well. If we get a big enough bid, every single player has a price.
"At the moment, I'm not 100 per cent sure what our team is going to be at Leicester. But we're not going to leave ourselves open.
"We'll get to a point where we'll have to say 'no' to any offers soon. We're still not safe in the league."
