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.
