Tottenham are chasing Lazio fullback Jordan Lukaku.
The Sun says Lukaku, who went to the Euros with his country, is seen as the long-term left-back option at White Hart Lane.
England's Danny Rose has established himself under Mauricio Pochettino but Ben Davies, 23, is his only back-up.
Lukaku, 22, would cost around £10million but has the potential for his value to grow.
He started at Anderlecht before moving to Pro League side Oostende for the last three seasons.
There he got on the radar for an international call-up to be team-mates with Romelu, 23, who scored for Everton at Manchester City this weekend.
