Tottenham have been told to up their bid for Roma striker Antonio Sanabria.

Sky Italia says Spurs have offered €9m for Sanabria after he rejected Rubin Kazan, but Roma want €12m.

Rubin Kazan did propose €15m for a transfer, but the player is not keen on moving to Russia.

Tottenham are very interested in the centre-forward, but so far their offer is only at €9m.
