Peterborough boss Darren Ferguson has admitted the League One side are unlikely to re-sign Craig Alcock.
Alcock, 26, made 39 appearances last season, but despite being released in May, Posh want him to re-join after losing fellow right-back Mark Little.
"I'm a very patient man and I've given Craig every opportunity without actually setting a time on it," Ferguson told BBC Radio Cambridgeshire.
"He hasn't come back to me, so I'm definitely looking at other options."
Ferguson added: "We've had meetings with him and [director of football] Barry Fry's offered him a contract, better than anywhere else I think.
"I've spoken to him about the football side of things. You've got to hope after that he gives a positive answer but he's not given anything so we will wait and see."
Manchester City player Adam Drury will join the League One side on their pre-season trip to Portugal with the Posh boss eager to take a more in-depth look at the 20-year-old.
The right-back made 14 appearances while on loan at Burton Albion between January and May 2013.
"Manchester City have allowed us to have a look at him and Drury's going to come to Portugal with us," he said.
"We know plenty about him already but it's good of City to let us take a proper look at him without having to sign anything straight away.
"If it's a positive feeling from myself then I'll speak with Manchester City. I've always said I prefer to sign players and have them as a Peterborough player than get them on loan but I don't know if that is something they're willing to do."
