Hughes has been linked with moves for Tottenham defender Michael Dawson and Real Madridâ€™s Ricardo Carvalho.
"There may be opportunities before the window closes where we once again have the opportunity to bring good quality players in,â€ť Hughes said.
â€śBut you have to wait and see. Sometimes you can do good deals right at the end of the window. On other occasions deals that you have set your heart on to conclude donâ€™t get done.â€ť
