It has also been reported that Aston Villa and Sunderland are monitoring the former Sheffield Wednesday star, who joined Forest in the summer of 2014.
Antonio was arguably Forest’s best player in the 2014-15 season and is one of their prized assets.
The Englishman scored 14 goals and created 62 chances in 46 appearances in the Championship, while having a pass accuracy of 60% and a shot accuracy of 44%.
Antonio is good enough to play in the Premier League, and one suspects that Forest could have to sell him this summer due to financial problems.
The Reds, who are under a transfer embargo, are aiming to challenge for a top-six finish in the Championship next season, but they should be bracing themselves for offers for their best players in the summer months.
