The Bayern Munich defender is a man in demand right now and he is wanted by the likes of Arsenal and Juventus as well.
According to Bleacher Report, Arsenal are keen on the player but Spurs are better placed to sign him.
Mourinho could use some depth in his back four and Boateng would be a good signing for Spurs.
He has the winning experience and the quality to improve Tottenham during the second half of the season.
Although the player is 31-years-old, he has a lot to offer and if Spurs can negotiate a reasonable fee with the German outfit, it could prove to be a wise addition.
