The World Cup group stage is over, and many players have caught the eye with their impressive displays ahead of the transfer window.
Group H was seen as one of the more dour groups at the World Cup before the tournament, but the surprise performances of Algeria made it far more interesting than expected. Belgium ran out group winners as anticipated, but were far less impressive that people thought they would be. Meanwhile, Russia and South Korea both limped out of the tournament without much of a whimper in hugely disappointing tournaments for both sides.
There were a number of players who performed brilliantly in Group H, with many of them coming from Algeria, including goalkeeper Rais M'Bolhi, midfielder Yacine Brahimi and striker Islam Slimani – but Chelsea should be looking to sign one of the Belgian stars who hasn't underwhelmed so far in Brazil.
Blues boss Jose Mourinho has already landed Barcelona midfielder Cesc Fabregas in a controversial £30m deal, but there could still be a need for midfield reinforcements. Ramires and John Obi Mikel have both been linked with exits this summer, and if even one of them does leave Stamford Bridge, then Mourinho will need to add another athletic player to partner Nemanja Matic.
One player that could fit that bill is Zenit St. Petersburg's Axel Witsel, who has featured heavily for Marc Wilmots' side. The 25-year-old has always threatened to be a star player during his spells with Standard Liege, Benfica and now in Russia too, and he has been instrumental in Belgium's midfield so far at the World Cup with his composure in possession and ability to keep the midfield ticking over.
Witsel was strongly linked with a move to Real Madrid when Mourinho was in charge of the Spanish giants, and it would no surprise to see him rekindle his interest in the Belgian. It would no doubt take a large fee to prise him away from Russian big spenders Zenit, but the Blues have a history of snapping up players from Russian clubs having signed Yuri Zhirkov, Willian and Samuel Eto'o in recent years.
