He tweeted: "BOOM! Chelsea in talks for Aguero!"
However, there is now some support for Manu Sainz's claim, with Sky Sports reporting that Chelsea do in fact have a "serious and strong interest" in signing Kun.
The Blues are hot on the pursuit for a new marksman this summer with Diego Costa likely to be sold between now and the end of the transfer window.
According to Spanish journalist Manu Sainz, the Citizens could sanction the sale of Aguero to their domestic rivals with Pep Guardiola open to the transfer agreement.
And after missing out on Romelu Lukaku to Manchester United the Blues have widened their search. He has brought in Gabriel Jesus, has maintained faith in the Brazilian young forward and seems keen on playing with one striker upfront, which means Aguero will be relegated to the bench.
And City star Aguero is now said to be on his wishlist with his future at the Etihad uncertain.
Aguero is widely regarded as one of the top strikers in the Premier League and it remains to be seen whether Manchester City would really consider letting him leave the club this summer, especially to join a title rival. It is hard to believe that Manchester City would sell to a direct title rival, especially after Chelsea won the Premier League last term.
