Fulham star Ross McCormack
The Owls came up short in their bid to reach the Premier League, as they lost the Championship play-off final 1-0 to Hull City at Wembley back in May.
Now, manager Carlos Carvalhal will be looking to mount another bid for promotion next season, and he appears to want more firepower in order to do it.
The Daily Mail report that Wednesday are looking to lodge a huge bid to sign Fulham striker Ross McCormack, almost a year since they failed in an initial move for him.
Sky Sports claimed last summer that Wednesday offered £10m to sign the Scot just days before the transfer deadline, but Fulham rejected the offer and kept him at Craven Cottage.
The Scotland international went on to hit 23 goals this past season, building on his 19-goal haul from the 2014/15 campaign - and his proven scoring record in the Championship has made him a top target for a number of clubs.
The Daily Mail claim that Aston Villa and Newcastle are already keen on McCormack, but Wednesday - backed by wealthy owner Dejphon Chansiri - are ready to compete by launching a huge offer to sign the former Cardiff and Leeds man in what would be a massively ambitious move from the Owls.
