Tottenham chairman Daniel Levy has ruled out the sale of Spurs' key men in the summer.
Englishmen Harry Kane and Dele Alli are both attracting interest from other clubs.
Spurs want to secure Kane's future with a new contract worth up to £200,000 per week, but he says talks are yet to begin and he has not been told of any coming up.
Meanwhile, Tottenham are prepared to offer Alli a deal approaching £100,000 per week.
