Bruce says 20-year-old Abraham is on his wanted list.
He explained: “I wouldn't want to comment on specific names, but he is one we're looking at."
Bruce is not optimistic about Le Havre defender Harold Moukoudi, however.
He added: “I think Moukoudi will stay in France.
“He's a bit reluctant because he's still young. That's the impression I get.
“We're down the line with a centre-forward because that's the area we're keen on, so we'll see what happens."
