The 22-year-old has only featured three times as a substitute this season, after joining the Owls in January.
His only goal in Owls colours came in last season’s 1-1 draw with Huddersfield Town.
Wednesday head coach Carlos Carvalhal believes a short-term move would benefit all parties.
“I have a player who I like too much, but he deserves much more than I can give him at this moment,” said Carvalhal.
“He’s a player now who is ready to play in England.
“He’s a very good striker, a good talent. I tried to give him short periods of play, but he deserves more. I recognise this. I believe he can score goals.”
Carvalhal stressed he had not spoken to Bus about a loan move, but several clubs have already enquired about his availability for a short-term move.
“Some clubs have started asking about him,” added Carvalhal.
“If he decides to go, they will have a very good striker ready for English football.
“He’s working very hard, has a good personality and has adapted to the English game.
“If he decides to go, I think it will be fantastic for him, the club he goes to, and also fantastic for us.”
Carvalhal is confident of fending off offers for his in-form players, who are on an 11-match unbeaten run, and revealed the Owls snubbed bids for goalkeeper Keiren Westwood and defender Tom Lees in the summer.
Owls goalkeeper Joe Wildsmith has been named in the England Under-21 squad for the European qualifiers with Bosnia-Herzegovina and Switzerland.
