The 22-year-old wide-man – who has four caps for Italy – has been one of the Naples side’s top performers in recent times, yet there is talk that he could be allowed to leave the Stadio San Paolo with Manchester United’s Shinji Kagawa a top target.
Insigne is valued at around £20m, which has alerted Spurs and Arsenal, who are both plotting to spend this summer.
Tottenham chief Daniel Levy is rumoured to be ready to launch big moves for players regardless of the Lilywhites’ current managerial situation in a bid to make this coming transfer window more of a success than last year’s alternative.
Arsenal meanwhile are also in the market for additions, with Arsene Wenger once again under pressure to draft in top quality players after letting an early title challenge slip away.
Napoli may well sell Insigne to aid their own transfer moves for Kagawa and Brazilian striker Leandro Damiao.
