The Owls have been linked with a move for Fulham's Neeskens Kebano as they look to strengthen for the second half of the season, but how much is their squad worth in the current market? Here's a breakdown of each player's valuation according to Transfermarkt.com and our opinions on those figures.
Transfermarkt value: 750k. Arguably a huge undervaluation of the Owls 'keeper, who is one of the best in the Championship and worth at least 3 million.
Transfermarkt value: 250k. Wildsmith has only played twice for the first team this season but would be an investment for the future, so would surely fetch a higher fee.

Transfermarkt fee: 100k. After his standout performances this season there's no way Dawson is worth anything less than a six-figure sum.
Transfermarkt value: 4m. Probably a fair estimate as most Championship defenders won't earn more than this sort of fee.
Transfermarkt value: 3m. Has had a strong loan spell with the Owls and is coming into his prime. Could probably do with a move away from Chelsea.
Transfermarkt value: 2.5m. Hasn't featured much for Wednesday so this might be a bit of an inflated value based on the fact he joined for 2m in 2017.
Transfermarkt value: 200k. Baker has broken into the first team this season with 12 appearances so far and his value will only rise with more minutes on the pitch.
Transfermarkt value: 1m. Pudil's stock has fallen in recent seasons, so a six-figure fee is optimistic considering he is out of contract at the end of the campaign.
Transfermarkt fee: 750k. Fox is still only 25 and despite a mixed spell at Hillsborough, would probably not sell for any more than what Wednesday payed for him.
Transfermarkt fee: 250k. Probably another case of youth and potential being undervalued by the market tracking website as Thorniley has played 18 matches for the Owls this season.
Transfermarkt fee: 200k. Broke into the first team this season but has fallen out of favour again now Jos Luhukay has gone. His value will surely only rise.
Transfermarkt fee: 500k. As a first team regular it's possible that Palmer is worth more than the figure quoted, but he's another player out of contract at the end of the season.
Transfermarkt fee: 2m. A fan favourite and regularly one of the Owls' standout players. Injury risk is the only thing that might limited this market valuation.
Transfermarkt fee: 1.5m. The Dutchman arrived at Wednesday for a reported 500k and his value has only risen according to the valuation site.
Transfermarkt fee: 500k. Possibly a fair estimation, but it's hard to put a price on Lee considering how long he's been out with injury.
Transfermarkt fee: 3m. Surely an undervaluation for the man that makes Wednesday tick and would be a huge addition to any team that signed him.
Transfermarkt fee: 1.5m. Seems a bit steep for a player who has been away from first team action for so long and is out of contract at the end of the season.
Transfermarkt fee: 750k. Another player out of contract at the end of the season and it's unlikely the 34-year-old stock will rise any higher than this fee.
Transfermarkt value: 1.5m. Boyd's value has apparently fallen according to the transfer estimation site, despite the fact that he joined Wednesday for free in 2017.
Transfermarkt value: 4m. Definitely an undervaluation of one of Wednesday's star men this season - with reports linking him with a 10m move in 2018.
Transfermarkt value: 3m. The Owls man has returned to parent club Tottenham due to injury but is due to be on loan at Hillsborough until the end of the season.
Transfermarkt value: 1.5m. The Portuguese winger's value has dropped during his time at Wednesday according to the transfer calculator.
Transfermarkt value: 7m. Forestieri has only played a bit-part role for the season but is still fancied as a top talent so could easily attract this sort of fee.
Transfermarkt value: 2.5m. Another player who has been out so long it is hard know his current value, but he is a proven goalscorer so could attract a large fee if he can rediscover his form.
Transfermarkt value: 2m. Has been Wednesday's star man in recent matches and proved he's still got plenty in his locker. Still a six-figure player.
Transfermarkt value: 2m. A talent who has plenty to offer for Wednesday, but his market value has plateaued according to the valuation site.
Transfermarkt value: 1m. Returning to regular first team action and will hopefully prove his credentials as a million-pound man in the remainder of the campaign.
Transfermarkt value: 500k. Is still a handful for opposition defenders and has something to offer, but is unlikely to attract a fee in excess of one million.
