Manchester United are interested in signing defender Tosin.
Sky Sports News has been told the 26-year-old is one of a number of central defenders United are looking at.
United are keen to speak to Tosin's representatives at the end of the season. He will become a free agent when his Fulham contract expires in the summer.
Sky Sports News reported earlier this month that Newcastle United and AC Milan were among a number of clubs interested in Tosin.
United are in need of central defenders, with Raphael Varane confirming on Tuesday that he would be leaving this summer as a free agent.
