"After completing successful medical tests, goalkeeper Simon Mignolet signs a contract for five years with Blauw-Zwart", a statement from Club Brugge read. Liverpool could receive an additional €2 million in add-ons.
Mignolet played just 180 minutes of football for the Reds last term as he warmed the bench, providing cover for Alisson.
But Mignolet has never hidden his ambition to be a consistent No1 again and the opportunity to head to Club Brugge in time to be registered for their Champions League qualifier against Dynamo Kiev - the first leg of which is on Tuesday night.
'The feeling of being on the pitch at the end when you have won is what I miss most.
That has presented itself with Club Brugge offering him a starting position as well as good contract terms, while the Reds will recoup almost all of the £9m they paid Sunderland to secure his services in 2013.
Whilst the Brazilian number one was afforded an extended break over pre-season, Klopp utilised the services of Andy Lonergan, a 35-year-old keeper who spent the second half of last season on loan at Rochdale.
The Belgian is understood to have travelled to Bruges following Liverpool's loss to Manchester City in the Community Shield on Sunday.
He then headed to take a flight to Brussels, where he was met by Club Brugge's president.
The 21-time Belgium worldwide returns to his homeland for the first time since joining Sunderland from boyhood club Sint-Truiden in 2010.
