Tottenham remain interested in signing Emerson, but face competition from a host of sides for the Real Betis defender.
The right-back is part-owned by Barcelona, who are eager to sell him.
As reported by Mundo Deportivo, Paris Saint-Germain, Inter Milan, AC Milan and Bayer Leverkusen are also monitoring the situation.
Tottenham are determined to improve their options at right-back this summer, with Matt Doherty having struggled since joining from Wolves.
Jose Mourinho can still call upon Serge Aurier, but 22-year-old Emerson, who was capped by Brazil at senior level in 2019, would provide some extra competition for places.
Tottenham were interested in Emerson last summer but a deal didn't materialise due to the financial restrictions caused by the coronavirus pandemic.
Barcelona and Real Betis secured the joint signing of Emerson from Atletico Mineiro in January 2019.
Emerson has been on loan at Betis for the past two and a half seasons, and it is possible that he could depart permanently this summer, with Barcelona and Betis sharing the percentage of a sale before January 2022.
