Martin O'Neill has urged Aston Villa's out-of-favour players to take heart from the example of Tottenham full-back Gareth Bale.
The likes of Steve Sidwell, Nigel Reo-Coker, Habib Beye, Nicky Shorey, Luke Young and Curtis Davies will be available to move if the price is right although they all have at least 12 months of their current contracts remaining.
But O'Neill points to Wales international Bale, who re-established himself at White Hart Lane under Harry Redknapp last season, as an example of how quickly situations can change.
He said: "Look at how Harry Redknapp has gone and re-entrusted players again like Gareth Bale. He was out of the picture at Tottenham, then came back into the side and did brilliantly.
"That sort of things happens at every club and I keep saying this to some of our players who have obviously been disappointed at not playing.
"It changes so quickly. You play really well in a game, you might get unlucky to be left out next time. But then, the second time, there's no reason to be left out and it just goes on from there."
