Wolves' Bakary Sako has revealed he is mulling over offers from the Premier League but is yet to decide on his future.
Rotherham boss Steve Evans will decide the fate of his out-of-contract players in a meeting on Monday.
Greek teenage winger Charis Mavrias has arrived in Sunderland for a medical ahead of a £2.5million move from Panathinaikos.
The 19-year-old Greece international, who has two caps to his name, has begun talks at the Stadium of Light.
Mavrias is the second youngest player to play in the Champions League - at the age of 16 years and eight months - and has since made more than 60 appearances for Panathinaikos, scoring six goals.
