The World Cup is not only football's biggest tournament, but it also serves as a shop window for players to impress onlooking clubs.
Liverpool's title challenge ultimately fell short as Manchester City stole in to take the crown in the final week of the season. Regardless of that late disappointment, Champions League football is finally returning to Anfield, and manager Brendan Rodgers will need to strengthen his squad if Liverpool are to compete domestically and in Europe.
There is bound to be a large transfer kitty at Rodgers' disposal this summer, and with the World Cup on the horizon, there will be a number of players catching his eye. Here are five players who will be playing in Group G that could be on Rodgers' radar this summer...
Ron-Robert Zieler, Germany
After Simon Mignolet endured an inconsistent first season at Anfield, and it's believed that Rodgers is looking to add another goalkeeper to push the Belgian. One of the names linked with a move to Merseyside is former Manchester United stopper is Zieler. Unlikely to play much of a part at the World Cup unless Manuel Neuer is injured or suspended, the Hannover goalkeeper has developed into a consistent player since leaving Old Trafford.
Thomas Muller, Germany
One of the more ambitious moves Liverpool could make this summer is to sign Bayern Munich forward Muller. The 24-year-old could leave the Allianz Arena, and whilst Manchester United are believed to be interested, Liverpool can offer Champions League football as they look to make their attack even more deadly. Alongside the likes of Luis Suarez, Daniel Sturridge and Raheem Sterling, the Reds would be all but unstoppable.
Emmanuel Agyemang-Badu, Ghana
Even after the capture of Bayer Leverkusen's Emre Can, Liverpool could still look to add more midfielders - particularly if Lucas Leiva or Joe Allen decide to leave the club. A reported target is Udinese's Agyemang-Badu, who at just 23, has the best years of his career ahead of him. An energetic midfielder who has a reputation for scoring goals from range, the Ghanaian could be a valuable addition.
Andre Ayew, Ghana
If Muller proves to be too expensive or he decides to stay with Bayern, the Reds may rekindle their interest in Marseille's Ayew. The French club have to sell this summer, and Ghanaian winger Ayew could be a bargain for the Reds. The 24-year-old declared his intention to move to Liverpool last summer, and having hit 49 goals in four seasons, Rodgers could add Ayew to his already fearsome frontline.
William Carvalho, Portugal
If Rodgers does look to add another midfield player, then they may vie with Manchester United for the signature of Sporting Lisbon's Carvalho. The 22-year-old Angolan-born anchorman has had a superb season in Portugal and is widely expected to continue his great form into the World Cup. He reportedly has a £37m price tag on his head, but his potential is huge - and he looks to be ideal for the Premier League.
