The 26-year-old has not played for the Owls since September due to a hernia injury.
Jose Semedo has insisted that his Sheffield Wednesday teammate Marco Matias will prove his class this season, after the 26-year-old endured a mixed start to life at Hillsborough, the Sheffield Star reports.
The former Portugal under-21 forward has been missing for the Owls since September due to a hernia problem, but the Star report that he is nearing a return, and Semedo believes that he will then provide the brilliance that the fans have been expecting.
"Marco is a real star. He has goals in him. He scored 17 in the Portuguese top-flight last season so I have no doubts whatsoever he can do well here," he said.
"When Marco recovers from his problem, he will shine just like Lucas Joao has for us. He will be like a new signing.
"The fans will love Marco as much as they love Lucas because he is a very good player. They have great knowledge and played well together at Nacional. They combine well and the fans will be happy to see them play together," he added.
Having finished last season behind the likes of Jackson Martinez as the fourth highest scorer in the Portuguese top flight, fans must have thought that they were getting a bargain when Matias arrived for just £1.14m (as reported by the Star).
However, since his move, he has managed just two goals in 11 appearances in all competitions. And in his absence, the likes of Lucas Joao and Fernando Forestieri have come in and propelled Carlos Carvalhal's side into play-off contention, which may make it harder for Matias to break back into the squad upon his return.
Despite the good form of others, Matias showed glimpses of real quality during the early part of the season, and that may be enough to see him earn an immediate recall to the side.
His magical goal against Leeds, in particular, suggested that he was a talent that could well be playing in the Premier League - as he calmly lifted the ball over the defender, before striking a stunning volley into the top corner to silence Elland Road - and Semedo believes that his teammate has the capability to take his side to the top flight with him.
