Gary Breen was released by Wolves after two years at Molineux

Walsall boss Jimmy Mullen has not ruled out signing former Republic of Ireland international defender Gary Breen.

Breen, 34, a free agent after leaving Wolves in the summer, has been linked with a move to the Saddlers.

Mullen told BBC WM: "There's nothing set in concrete at the moment but there's one or two irons in the fire.

"You don't need transfer money necessarily. I've brought players here on free transfers and there are still some in that situation."

Although he would like to strengthen his squad, Mullen is looking forward to getting some of his current key men back available.

"Once we get our injured players back - Steve Roberts, Dwayne Mattis and Rhys Weston - and have Michael Ricketts free from suspension we've got four quality players to add to the squad."

Mullen also revealed that trialist Nick Chadwick has not been offered a contract at the club and has been released.

"I had a chat with Nick and I just felt with Troy Deeney, Jabo Ibehre and Ricketts, he'd be a bit too similar to what we've already got.

"He took it well. We've been good for him and he's been good for us."
