In a statement released earlier, Club Brugge wrote "After completing successful medical tests, goalkeeper Simon Mignolet signs a contract for five years with Blauw-Zwart. Liverpool FC, Club Brugge and Simon reached an agreement on this today."
Liverpool will receive an initial fee of £6.4m (around 7 million euro) with a further £1.8m (around 2 million) in add-ons, having granted the 31-year-old’s wish to leave in search of regular first-team football.
Simon Mignolet played 204 times for Liverpool following his 10 million-euro transfer from another English club Sunderland in 2013. However, he has been the second choice keeper at Anfield over the past 18 months, having lost his place to Loris Karius. He made just two first team appearances last season.
Mignolet was keen to leave last summer but Liverpool refused a loan offer from Napoli, preferring instead to send Karius to Besiktas.
Mignolet was on the bench as Liverpool lost the Community Shield on penalties to Manchester City at Wembley on Sunday, but flew straight to Belgium afterwards to finalise his move.
Club Brugge were keen to get the deal done before their Champions League qualifier against Dynamo Kiev on Tuesday night.
