And, according to Wallace, Semedo is trying everything to try and win his spot in Carlos Carvalhal’s starting line-up back.
“Semedo trains like an animal every day and I’ve got the marks to prove it,” the Wednesday winger said.
“He trains hard every day and is so professional so there are a lot of options for the manager.”
Semedo has dropped out of favour at Wednesday this season, and he has found chances hard to come by.
The combative midfielder has been a key player for the Owls in previous campaigns, but their squad is now of a higher standard, and he has found it hard to dislodge the likes of Barry Bannan and Sam Hutchinson on a regular basis.
Semedo has made just 15 appearances in all competitions, and he last featured in a Wednesday match way back in January.
Wallace, meanwhile, has played far more frequently for the Yorkshire side since arriving on a free transfer last summer.
Wallace has played 38 times for Wednesday in the Championship, and he has been able to score on three occasions.
