Chelsea have reached terms over their first signing of the summer.

The London Evening Standard says terms have been agreed with the player, but the club have decided to delay confirmation until the start of next month.

Chelsea are looking to make up to six transfers during the window, with players such as Romelu Lukaku and Tiemoue Bakayoko their main targets.

While the club wouldn't confirm who they have acquired, it is believed the most likely candidate at this stage is former Manchester City keeper Willy Caballero.

The champions are looking for a new backup keeper to Thibaut Courtois having sold Asmir Begovic to Bournemouth for £10million earlier this month.
