Belgian international goalkeeper Simon Mignolet became the fourth signing for Premier League side Liverpool's on Tuesday when he moved from Sunderland for £9m.
The 25-year-old, who signed a long-term contract at Anfield, joins Manchester City's veteran defender Kolo Toure, Sevilla's Luis Alberto and Celta Vigo's Iago Aspas as manager Brendan Rodgers' new recruits since a disappointing season saw them fail to qualify for Europe in finishing seventh and without a trophy.
"I am delighted that we have been able to sign one of the top goalkeepers in the Premier League," Rodgers told the club's official website.
"Simon will join a club that will give him an opportunity to demonstrate and improve his huge talent."
Mignolet, who played over 100 games for Sunderland since a £2m move from Belgian side Saint-Truiden in June 2010, could well replace the club's long-time No1 Spaniard Pepe Reina, who has been linked with a move to La Liga champions Barcelona.
Rodgers' spending is far from over as he has also declared an interest in highly-rated Sporting Lisbon defender Tiago Ilori, 20, and 24-year-old Armenian midfielder Henrikh Mkhitaryan from Ukrainian giants Shakhtar Donetsk. However, he will face a battle with other clubs to secure the signature of Mkhitaryan, who is valued at £20m.
