The emergence of new teams has upped the competition among teams and the excitement amongst fans is only set to grow from here. Many big teams have stumbled in the group of 32. Germany losing to Mexico and Brazil's disappointing start are not what fans had expected. While one may argue that the expectations and the attention on the likes of Lionel Messi and Christiano Ronaldo are misplaced, the time is apt to look out for some players who may be playing their last World Cup. Here are 5 players who could retire after FIFA World Cup 2018: 1. Andres Iniesta Andres Iniesta, 34-years old, is one the most prominent players in the football world. Iniesta has recently retired from his club Barcelona after playing for 16 long years and may retire from the Spanish team too. With terrific dribbling techniques and control over the ball, Iniesta's talent was an important asset for the team. Iniesta's retirement will be a great loss for the team and might be an end of an era in Spanish Football. Having appeared for 3 times in the World Cup, the 4th might be the time for him to hang his boots. 2. Thiago Silva Brazillian footballer, Thiago Silva is an important center back defender in both Paris Saint-Germain (PSG) and his national team Brazil.

The 33-year-old striker is another football star known by everyone across the globe.
