Boyce, who had a spell at Werder Bremen earlier in his career, has been in superb form for Northern Ireland Premier League leaders Cliftonville, netting 22 goals so far this season.
The 21-year-old's performances have not gone unnoticed among clubs in England with a host of scouts flocking to Solitude to watch the Northern Ireland international in action.
The likes of Blackburn, Burnley and Wolves are all thought to have watched Boyce in action this season as they keep tabs on his progress.
Boyce's agent, Stephen Whelan, is aware of the rumoured interest in the free-scoring striker, but insists he has had no contact with any interested clubs.
"I am aware that clubs have been watching Liam this season as he done very well for Cliftonville," Whelan told Sky Sports.
"I have not had any official contact with any interested clubs and until that happens Liam will continue to give his all his Cliftonville.
"He is enjoying his football and he is just focusing on helping Cliftonville achieve their goals this season."
