The Romanian forward has played just three times this season for the Owls, and he has slipped even further down the pecking order following the arrival of Gary Hooper at the club.
As a result, Carvalhal wants to allow Bus to leave on a temporary basis, as he feels the 22-year-old deserves better than sitting on the bench.
CC: Sergiu Bus is a player who deserves more, he is ready to play, he works hard and a loan move would be good for him #swfcLIVE— Sheffield Wednesday (@swfc) November 5, 2015
Bus was brought to Wednesday at the start of 2015, but he has not made the desired impact at the Yorkshire outfit.
When he has played, he hasn’t had a particularly prolific scoring record and with standards rising at Hillsborough, he was unlikely to last long.
Bus, himself,has commented on his desire to leave the club on loan, in the Sheffield Star, as he is desperate to start playing regularly again.
Bus has been a potent scorer on the continent, and Wednesday will hope that some time away from the club can get him back to his very best again.
