Barcelona are eyeing Manchester City striker Sergio Aguero as his contract runs down.
The Sun says the 32-year-old Argentine is out of contract in the summer, which means he can talk to European clubs about a free transfer.
And that has alerted Barca, who are keen to bring the ex-Atletico Madrid forward back to Spain.
Aguero is still waiting for a new deal offer from City, where he has been for nine years.
As well as interest from the Nou Camp, Aguero — City's all-time leading scorer — is also wanted by Mauricio Pochettino, the new boss of Paris Saint-Germain.
Aguero has won four Premier League titles, five EFL Cups and one FA Cup during a trophy-filled spell at the Etihad.
