In pictures: World Cup 2014 – 10 to watch in Group F

Edin Dzeko, striker (Manchester City); age 28; 58 caps. The robust and versatile striker is the tip of Bosnia’s spear and he will have to shoulder huge expectations from the Balkan country’s fans and pundits in Brazil. One of the most recognised scorers in the game, Dzeko also has the ability to hold the ball, take on defenders and assist his teammates. Known as “The Bosnian Diamond”, he is the Balkan country’s all-time leading scorer with 33 goals. Michael Regan / Getty Images

John Obi Mikel, midfielder (Chelsea); age 27; 58 caps. He is used in a more attacking role by his country who do not have a playmaker but is much more effective as a crunching midfielder. Obi Mikel, who, as a teenager, was the subject of a tug of war over his services between Chelsea and Manchester United, has not been able to command a regular berth at his London club. His real name is John Obinna but the Obi Mikel tag has stuck since the Nigeria Football Association botched his paperwork ahead of a Fifa youth tournament. Missed the last World Cup through injury.

Sergio Aguero, striker (Manchester City); Age 26; 50 caps. Nicknamed “Kun” after a Japanese cartoon character, Brazilian clubmate Fernandinho says he is one of the funniest people he knows. A regular scorer for his club side, with tremendous ability and agility to turn defenders, a penalty box menace for the best defences, he has 21 Argentina goals.

Gonzalo Higuain, striker (Napoli); Age 26; 36 caps. Brilliant finisher who scored a World Cup hat-trick against South Korea in 2010, he was also eligible for France having been born in Brest where his defender father “Pipa”, hence the nickname “Pipita”, played. An intelligent player who prefers to run onto passes but will also do a good job with his back to goal holding the ball up, he has a tally of 20 international goals. Eduardo Di Baia / AP

Vedad Ibisevic, striker (Stuttgart); age 29; 51 caps. Thrived alongside Dzeko in the qualifiers as the two combined for 18 of Bosnia’s 30 goals. A perfect complement to his more heralded strike partner, Ibisevic got just reward for his hard work when he scored the winner in a 1-0 defeat of Lithuania, which sealed Bosnia’s berth in the finals.

This season he has been on loan at Liverpool, featuring mainly in his favourite left wing position. Afolabi Sotunde / Reuters
