The one Group C player Chelsea should sign after the World Cup

Sokratis Papastathopoulos Greece

The World Cup group stage is over, and many players have caught the eye with their impressive displays ahead of the transfer window.

Group C saw dark horses Colombia live up to their billing despite the absence of star striker Falcao, winning all three games whilst there was drama in the final round of matches as Greece scored an injury time penalty against Ivory Coast to dump the Africans out of the tournament. Japan were massively disappointing given the expectations before the competition.

There have been plenty of fine performances in Group C, from James Rodriguez and Juan Cuadrado's sensational attacking play for Colombia, to the defensive displays of Greek centre back Sokratis Papastathopoulos – and Chelsea should certainly be looking to add one of those three players ahead of the new season.

The Blues have already allowed centre back David Luiz to leave the club in order to join Paris Saint-Germain, and with John Terry's career ultimately coming towards the end, manager Jose Mourinho must be looking to bring a defender as he looks to plan for the future. Gary Cahill has been effective over the past year, but finding another centre back who can contribute immediately would take some of the pressure off new signing Kurt Zouma.

Greece have advanced through the group stage in predictably dour fashion, forcing a 0-0 draw against Japan before snatching an injury time penalty to beat Ivory Coast and setup a meeting with Costa Rica in the last 16 – and they couldn't have done it without their talismanic defender Papastathopoulos.

The Borussia Dortmund man, 26, has proven his worth as one of the top defenders in Europe during the World Cup, marshalling a stern Greek defence effectively throughout. Yet with the likelihood of being sat behind Neven Subotic and Mats Hummels at Signal Iduna Park,there could be the possibility of the former Werder Bremen man moving on this summer – and Mourinho should be watching with intent after he impressed in Brazil.
