Chelsea have made their first signing of the summer but don’t plan to announce it until July 1.
Standard Sport understands that 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.
The 35-year-old is a free agent after being released by Manchester City. His experience of Premier League and Champions League at Etihad Stadium makes him the perfect support for first choice Thibaut Courtois.
Negotiations with Caballero stepped up over the past week and it would be a surprise if he doesn’t move to Stamford Bridge.
Chelsea may decide to bring the announcement forward, but the plan at the present time is to announce the signing at the start of July.
