Arsenal are keeping tabs on Sergio Aguero's situation at Manchester City.
Despite Pep Guardiola's public support of the Argentine, there remains a belief across Europe that he's prepared to see Aguero sold, says Don Balon.
AC Milan and PSG have been linked in the past week, but Arsenal are also interested and eager to keep him in England.
Chelsea and Tottenham are also being mentioned as potential suitors.
Arsenal boss Arsene Wenger would love to work with El Kun and should he become available, the Londoners will be quick to act.
Real Madrid hve been long-term suitors, but are out of the equation as they face a 2017 transfer ban.
Aguero was a late second-half substitute for last night's EFL Cup defeat to Manchester United.
