Sandwell-born Chambers, who joined the Saddlers from Leyton Orient in the summer of 2011, missed almost all of last season after breaking his foot in the opening day clash against Plymouth Argyle and still hasn’t fully recovered from that injury, suffering several setbacks along the way.
The 38-year-old, who has made well over three-hundred appearances in a Saddlers shirt, was club captain for the past five years and is understood to be considering his options - which includes the possibility of retirement - as he continues on the road to recovery.
Mansfield-born Clarke, who has already added midfielders Stuart Sinclair, James Hardy, and Jack Kiersey to his squad, revealed that has spoken to Chambers a number of times over the summer and says an offer to join training as a trialist will remain on the table for the midfielder
Speaking via the Express & Star, Darrell said; "I have spoken to Adam and there is an offer open if he wants to continue playing. But he is injured. He is welcome at the club and for me to assess him.
"But I don’t know what Adam is planning. I have told him to pick up the phone if he is ready to stay in football and have a go. If he wants to come in he will be assessed as a trialist."
Despite several rumours suggesting Adam also has an offer to join the club's coaching set-up, Clarke revealed that neither he nor the club had made an offer that would see Adam join the coaching staff.
Clarke added; "There is no coaching role for Adam. I’m not sure where he wants to take his career at the minute. He is still having problems with his foot."
