Liverpool completed their fourth signing off the summer on Tuesday as part of an active summer transfer period following a disappointing finish to the 2012-2013 Premier League season.

Goalkeeper Simon Mignolet joined the Reds on a £9 million deal after joining Sunderland in 2010. He becomes the first Belgian player to ever play for Liverpool. Upon passing a physical, the 25-year-old joins defender Kolo Toure from Manchester City, attacking midfielder Luis Alberto formerly of Barcelona, and Sevilla’s Iago Aspas as the Liverpool’s freshest faces.

"I am delighted that we have been able to sign one of the top goalkeepers in the Premier League," said manager Brendan Rodgers, on the club's official website.

All four moves have addressed the club’s glaring needs across the pitch, but more are reportedly on the way, including overtures to two players currently residing in Germany.

Rodgers continues to pursue a center back, and according to The Sun, he’s engaged in a battle with Premier League rivals Arsenal for Schalke’s top rated Kyriakos Papadopoulos. The move could cost upwards of £12 million for the 21-year-old who has made 57 appearances in Germany since transferring from Olympiakos in 2010.

In March, Liverpool also had interest in Werder Bremen winger Eljero Elia, and the club reportedly still want to sign the 26-year-old. The Dutch star made 21 appearances, scoring no goals for Werder Bremen last season.

Talk Sport pointed out Elia’s trouble with coaches, which could be the reason he’s played for five different teams since 2004. Elia has also spurned Liverpool’s advances before, choosing Juventus in 2011. However, that move proved ill-fated, as Elia made only four appearances.

Elia has experience on the international level. He’s earned 27 caps and two goals for the Netherlands since 2009.

Liverpool could also scoop up Wigan striker Arouna Kone, according to The Sun. Kone wants to no part of the Latics relegation to second division, and said he wants to stay in the EPL.

“I’m under contract with Wigan for two more years,” Kone said to The Sun. “But if there is an offer that is good for both me and Wigan I will seek to leave.”

It’s safe to say the 29-year-old did his part to help Wigan, leading the club with 13 goals and the FA Cup title last season. The Ivory Coast international has a release clause in his contract, setting his price at £6.5 million, according to the Daily Mirror, though Kone wants to follow Roberto Martinez to Everton.

Kone has also turned down offers from Norwich City and Swansea City.
