Phil Brown has not ruled out making a permanent move for Manchester United striker Manucho.
The Angola international spent the second half of the season on loan at the KC Stadium and scored two goals in 17 appearances for Hull City.
He has now returned to Old Trafford and has 18 months remaining on his United deal, but Brown is considering a summer swoop.
The Tigers boss is keen to sign two forwards during the transfer window and admits he could be tempted to recruit Manucho, but only if he can agree on a price with United.
"There's mileage in Manucho but how much there is would depend on how much he would cost us," Brown told the Hull Daily Mail.
"He's 6ft 4ins, he's got an eye for goal, he's got pace and he's got an awareness in the penalty box.
"There's certainly potential where he's concerned, but he's a very raw talent."
There has been speculation that Hull could raid Newcastle, Middlesbrough or West Brom, who all dropped out of the Premier League at the end of the season.
Chairman Paul Duffen has refused to confirm the rumours but admits the club will have to 'look at everything'.
Duffen added: "The market is starting to creek and groan a little now and there is starting to be some movement.
"It is an interesting market this summer as the global economic situation will mean clubs will have to be careful with their finances.
"Obviously there are also players who will attract interest at the relegated clubs. The problem with going down that route is that many players have long contracts and high salaries that they are happy to sit on."
