Sheffield United are giving a trial to former Bolton and Portsmouth midfielder David Thompson.
Blades manager Bryan Robson told BBC Radio Sheffield: "He's out of contract at the moment and is trying to build up his fitness.
"There are quite a few clubs that are interested in him and I'm glad he's decided to come to us."
Robson added: "I can't say how long he'll be with us but he'll train with the first-team and we'll assess his fitness.
"When he's fit he's a very good player so it's definitely worth having a look at him."
