Tottenham are following Rennes defender Jean-Armel Kana-Biyik.
The 22 year-old, though tied to Rennes until 2015, is expected to be cashed in by Rennes this summer.
Lyon are already in contact with Rennes for Kana-Biyik, though those close to negotiations are flagging the interest of Spurs and AC Milan also in the young stopper.
