A number of Premier League clubs are said to have been alerted by Moussa Dembele's reported unrest at Tottenhm Hotspur.
The 26-year-old Belgian has seen his first-team opportunities restricted at White Hart Lane and is believed to be considering a move in January with a place in Marc Wilmots's squad for next summer's World Cup at stake.
Dembele has started two of the last five Premier League games and voiced his frustration to Belgian newspaper Nieuwsblade, who quote him as saying: "I can not be satisfied with it, of course, I just want to play as many games.
"The coach explained that he makes a tactical choice, he wants more defensive players in midfield."
According to the Daily Express, Newcastle United, Aston Villa, Southampton, Cardiff City and Swansea City are among those tracking developments in North London.
Napoli are also rumoured to be interested in the former Fulham midfielder, who joined Spurs for £15m in August 2012.
