Chambers, who will be out-of-contract later this month, is yet to fully recover from the foot injury he sustained on the opening day of last season and is understood to be considering his options, including the possibility of retirement, with Clarke insisting an invite to attend pre-season training remains on the table.
The midfielder has made more than 300 appearances since joining the Saddlers in July 2011 and been offered the chance to both continue his playing career whilst joining the club's coaching team, giving him the chance to share the wealth of knowledge he has amassed over his nineteen-year career.
Speaking via the Express & Star, Darrell said; "I have had a couple of conversations with Adam and we’ll see how that develops.
"There is no rush. He is out of contract and it was a case of him being welcome to come into pre-season to have a look and see where his fitness levels are.
"He has been a great servant to the club and it was a respectful thing for me to do. The door is open if he wants to come in and do some training."
