The Argentine ended his glittering 10-year tenure with Manchester City earlier this year, and Barcelona won the race for his service despite reported interest from several Premier League teams.

Agüero’s farewell season at Etihad, however, was not a memorable one as he only scored six goals in all competitions while struggling with injury issues.

Given the abundance of offensive talent available to Ronald Koeman, AS reports that Aguero has accepted his role as a rotation player. </ Memphis Depay have also arrived at Camp Nou on a free transfer from Lyon but there are doubts about the future of Lionel Messi, Antoine Griezmann, Philippe Coutinho and Ousmane Dembele.

However, Barcelona are said to face crippling debts of over £ 1bn be, and signings like Aguero can allegedly only be registered once the club has further reduced its payroll.
