Robert Earnshaw is the subject of interest from Sheffield United and could leave West Bromwich Albion to join the Coca-Cola Championship club when the transfer window opens in January.
But Sheffield will only make their offer for the Wales international striker, believed to be in the region of £2 million, if Neil Warnock remains as their manager.
Warnock is being pursued by Portsmouth and could leave Bramall Lane for Fratton Park next week.
If he opts against a move to Portsmouth, he will also try to sign Andy Johnson from Albion on a free transfer.
Earnshaw and Johnson are playing less first-team football than they would like and wonder if they are part of Bryan Robson's plans.
The former joined Albion for £3 million from Cardiff City in the summer of 2004 and has scored 12 Premiership goals in 40 matches.
The latter, who came close to joining Coventry City on loan in October, joined Albion from Nottingham Forest in September 2001 for £200,000. He has played 127 Premiership matches for Albion and played a significant role in the promotion teams of 2002 and 2004.
Johnson's contract runs out at the end of the season but it seems likely that Albion would allow him to leave on a free transfer in January. That would allow him to pursue first-team football and would enable Albion to save on his wages.
Earnshaw's possible departure is more difficult to work out. Like Johnson, he is popular among Albion supporters but has failed to establish himself as a striker around whom Robson would want to build a team.
There is also talk that, if Warnock does leave Sheffield, he will try to sign Earnshaw for Portsmouth.
Nigel Pearson, Robson's assistant, said last week that Earnshaw remains an important part of the Albion squad but the club have six strikers and keeping so many happy will prove to be one of Robson's toughest challenges this season.
Sheffield seemed destined for promotion to the Premiership - they are in second position in the Coca-Cola Championship, nine points clear of third position - and have the resources to build a strong squad.
Milan Mandaric, the Portsmouth chairman, is hoping to secure a deal before next week for the next manager at Fratton Park after revealing that Warnock is a target.
Sheffield will be offered a financial compensation package, while Portsmouth were last night refused permission to speak to Alex McLeish, the Rangers manager, who has endured a wretched domestic season but is within sight of the Champions League knockout stages.
Mandaric has also had an approach for Iain Dowie, the Crystal Palace manager, turned down and has the option of bringing Sir Bobby Robson out of retirement after a year out of the game.
Mandaric said: " We know Neil is there and I hope we will be able to put that package to him and Sheffield United if he remains to be our No 1. If not, equally there are two or three other people and we'll look at that in the next 24-48 hours.
"I want this decision to be made no later than the first part of next week."
While Mandaric wants the deal completed as soon as possible, he would be prepared to wait for Warnock to take charge if the Blades manager wanted to be at the helm for the derby clash with Sheffield Wednesday at the weekend.
