Stuart Gray is not taking for granted the re-signing of out-of-contract players.
The Owls manager knows full well that Glenn Loovens, Oguchi Onyewu, Chris Kirkland and Jose Semedo could end up going elsewhere.
But Gray is confident that the club are doing all they can by offering new deals to the quartet and engaging in negotiations.
“It’s question of whether players think the grass could be greener on the other side,” he told The Star.
“We have shown our faith in the lads and desire to retain them, and hopefully they will stay.
“We hope we can build on what we achieved in the second half of the season.”
With attempts to bring in new players continuing as well, he added: “You make your plans but often they do not fall into place straight away.
“The thing tends to be agent-driven; agents are talking to clubs, and in some cases players are on holiday.
“Agents can want their players to wait and see what might come in.”
Kirkland and Semedo are both on public record as saying that they want to stay - possibly a good sign for the club.
Gray has also seen signs that Oguchi and Loovens are willing to extend their stays, and confirmed that he remains in interested in Sam Hutchinson, who was a hit while on loan from Chelsea.
But as in the case of other loan signings, Gray believes that Hutchinson’s form may have alerted competition.
Wednesday have lodged offers with the agents of certain out-of-contract players but continue to await answers.
