The young Sunderland striker has found first-team opportunities limited at the Stadium of Light, and is relishing the prospect of regular football in the Championship
The England Under-21 international, who signed for the Black Cats from Ipswich Town in 2011 for an initial £8 million, has found first-team opportunities limited this season, having made only nine league appearances in the whole campaign so far.
Wickham, whose only goal this term came in the 2-2 FA Cup draw away to Bolton, will be looking to contest for a regular starting place for the Owls, a prospect that he is relishing.
He told Wednesday's official website: “I need to play games and after speaking to the manager and with the size of the club, I jumped at the chance to come here.
"It’s always important to have the manager’s backing and hopefully I can come here and make an impact."
Wickham also reflected on his desire to start finding the back of the net for the Owls and believes he can help his new club maintain their Championship status.
He added: “As a striker you want to score in every game. I want to come here and show everyone what I’m capable of.
“My confidence is high and hopefully I’ll add another dimension to the team.”
