Bruce's bid to lure DJ Campbell from QPR has been placed on hold following initial talks and although goalkeeper David Stockdale has arrived on loan and midfield pair Robbie Brady and David Meyler have signed permanent deals during the transfer window, a goalscorer is proving hard to find.
"We're nowhere near anything at the moment, I've got to be honest and portray that," Bruce told the Hull Daily Mail after his side's FA Cup exit at the hands of Barnsley at the weekend.
"We'll have to see what develops, but it's proving to be a very difficult window at the moment.
"There's lot of names being bandied around, but we're honestly not close to anything right now."
Bruce's previous target Fraizer Campbell chose to join promotion rivals Cardiff earlier in the month and the Tigers have struggled in front of goal since Aluko was diagnosed with a torn Achilles two weeks ago.
