Reports have mentioned the club in connection with Gabriel Batistuta of Roma, FC Copenhagen's Bora Zivkovic, and Monaco's Shabani Nonda, but Glenn insists: "There is nothing to say. There is lots of speculation about at the moment, not just concerning West Ham and what players might be coming to us, but linking players with all the other Premiership clubs.
"It is suddenly transfer season getting close to being up and running, and the papers haven't had anything to write about in terms of transfer news over the last few months.
"All their attention has been elsewhere on other matters, but now the transfer window is about to open and everyone is being linked with all sorts of players.
"The player Nonda is a top goalscorer in France for Monaco so I am very aware of him - he is an excellent player, and for some reason we have been linked with him."
