Barcelona defender Emerson is thought to be a man in demand this summer.
According to Mundo Deportivo (via Sportwitness), Newcastle, Everton and Tottenham are keen on the player.
Spurs were linked with the player earlier this year as well.
It will be interesting to see which of three clubs come forward with an offer first. All three clubs could use a right-back next season and Emerson would be a good signing for them.
Emerson is part-owned by Betis and he has been on loan at the club. The defender could be made available for transfer this summer.
