Tottenham are launching a swap bid for Lyon midfielder Houssem Aouar.
Spurs are ready to make an offer for the France international, says Le 10 Sport.
Lyon are seeking €20-25m to sell Aouar.
And Spurs hope to keep down the cash component by including Tanguy Ndombele in their proposal.
It would mean a return to OL for Ndombele, who left two years ago for £60m.
