Tomori could be on the move from Chelsea before the transfer window closes this month as he looks to enjoy regular game time.
The centre-back has attracted interest from AC Milan, who are mulling a move for him as a potential extra option in defence for the second half of the season.
However, the Rossoneri face competition for Tomori from an unnamed Premier League club.
Tomori has been linked with Leeds United and Newcastle United, but neither club are battling for his signature at present.
There is also interest in the Chelsea man from a side in La Liga.
Tomori could be presented with choosing between moving to Serie A, La Liga, or staying in the Premier League.
The 23-year-old has slipped to fifth in Frank Lampard’s pecking order of centre-backs and the Blues are ready to sanction his departure if the deal makes sense.
Tomori has made just four appearances for Chelsea over the course of the season so far.
