World Cup 2014: Five Group A transfer targets for Tottenham - United striker features

Javier Hernandez celebrates goal for Mexico

The World Cup is not only football's biggest tournament, but it also serves as a shop window for players to impress onlooking clubs.

Spurs' season ended on a high with a 3-0 win over Aston Villa on Sunday, but it wasn't enough to keep Tim Sherwood in charge at White Hart Lane, as the former England international's six month stint as manager was brought to an end on Tuesday.

Despite splashing out almost £100m on new players last summer, Tottenham are now expected to spend again in order to improve their squad, with most of last year's arrivals flattering to deceive. Some of those players are bound to be in World Cup action this summer, so here are five potential targets playing in Group A at the World Cup that could be on Spurs' radar this summer...

Luiz Gustavo, Brazil

Whilst Arsenal were the team most strongly linked with a swoop for Gustavo whilst the midfielder was with Bayern Munich, Spurs have been credited with an interest in the former Hoffenheim man since he moved to Wolfsburg. A strong midfielder who is adept at breaking up play, it's no surprise that Gustavo has so many admirers around Europe, and the revelation that he has a £20m release clause in his contract at Wolfsburg means impressive displays at the World Cup could finally see him move to the Premier League.

Alex Song, Cameroon

Former Arsenal midfielder Song impressed in the Premier League with his powerful displays, but has failed to make an impact with Barcelona since moving in 2012. It now appears that the 26-year-old will be sold this summer as part of Barcelona's plans to rebuild the squad, and with a cut-price deal on offer for the defensive midfielder, Tottenham have been linked with a swoop - particularly as it seems Brazilian midfielders Sandro and Paulinho could leave the club this summer.

Vincent Aboubakar, Cameroon

Offered trials by Spurs as a 17-year-old, Aboubakar has blossomed this season, hitting 16 goals and laying on seven assists in a superb season for Ligue 1 side Lorient. Whilst it remains to be seen whether the club are still interested in the Cameroon international, Aboubakar has emerging as one of the top young striking talents in Europe and Spurs are still in desperate need of firepower after losing Jermain Defoe to Toronto and seeing Roberto Soldado struggle since his move from Valencia.

Dejan Lovren, Croatia

Since Spurs sacked manager Sherwood on Tuesday, Southampton boss Mauricio Pochettino has become the firm favourite to take the reins at White Hart Lane. His star centre back at St. Mary's Stadium has been Croatian international Lovren, and with Spurs desperately needing to add some talent to the heart of their defence, bringing Lovren to North London with him would seem like a sensible move for Pochettino - if he does indeed get the job.

Javier Hernandez, Mexico

Manchester United striker Hernandez has seen first team opportunities hard to come by this season, with Robin van Persie, Wayne Rooney and Danny Welbeck ahead of him in the pecking order. That has led to some speculation that the 25-year-old will look to leave Old Trafford this summer, and with Spurs needing to boost their strike force, the Mexican has been linked with a move to White Hart Lane. With Tottenham in contention for a top four place alongside United, they may be uneasy about selling a goalscorer to them, but Hernandez wants football - and Spurs can offer it him.
