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 E that could be on Rodgers' radar this summer...
Mathieu Valbuena, France
Rodgers has been seeking to add another attacking midfield player for around a year now, but after missing out on Henrikh Mkhitaryan, Willian, Mohamed Salah and Yevhen Konoplyanka, he has to wonder if he will ever manage to sign another one. Fortunately, rumoured target Valbuena is tipped to leave Marseille this summer as the French club look to cut their costs, and the diminutive playmaker should impress at the World Cup.
Loic Remy, France
Liverpool still need to add some striking depth behind the likes of Luis Suarez and Daniel Sturridge, particularly as Iago Aspas has failed to impress since signing from Celta Vigo last summer. The Spaniard could leave the club and in his place, QPR's Remy could arrive after a superb loan spell with Newcastle United. The pacey Frenchman has admitted that the World Cup this summer is his shop window - and Liverpool will be watching with intent.
Ricardo Rodriguez, Switzerland
After Jose Enrique sustained a season-ending knee injury, Liverpool were left short at left back and had to shoehorn Glen Johnson or Jon Flanagan there. As a result, Rodgers is likely to add another left back this summer and highly-rated 21-year-old Rodriguez will no doubt be on his shortlist. The Wolfsburg star has impressed hugely in Germany this season, and is expected to carry on that form into the World Cup.
Gokhan Inler, Switzerland
Adding more depth in midfield is another concern for Rodgers, and Napoli's Inler was strongly linked with a move to Merseyside in January in a swap deal involving defender Daniel Agger. The powerful midfielder has impressed in Serie A during spells with Udinese and then Napoli, and will be the driving force in Switzerland's midfield this summer - where he can prove to Rodgers that he has what it takes to adjust to the Premier League.
Xherdan Shaqiri, Switzerland
Rodgers' pursuit of attacking midfield or wide players has led to Bayern Munich's Shaqiri being heavily linked with the club. The 22-year-old has struggled to break into the Bayern first team and is behind Arjen Robben, Frank Ribery and Thomas Muller in the pecking order, leading to some suggestions that he will leave the club. With a big World Cup predicted for the Swiss star, Liverpool will be keeping tabs on his progress.
