Chelsea are ready to launch a £60m bid for Manchester City striker Sergio Aguero.

The Mirror says Chelsea want Aguero to replace Diego Costa.

The champions are poised to take advantage of the Argentine's uncertain future at Manchester City .

After losing Romelu Lukaku to Manchester United, Chelsea are ready to test City's claim that they are determined to keep Aguero at the club.

Aguero was only recalled to City's starting line-up last season when injury struck Gabriel Jesus in early February, ruling him out until the final few games of the season.

And with City's regular wide roles likely to be occupied next season by young duo Leroy Sane and Raheem Sterling, Aguero could yet find himself surplus to requirements.
