Aguero’s continued absence means that one of Ezequiel Lavezzi and Maxi Rodriguez is likely to start again, with the former seemingly sitting in pole position for a starting berth.
Belgium boss Marc Wilmots, meanwhile, received some encouraging news from the treatment table concerning the fitness of Thomas Vermaelen, with the Arsenal man ready to make his comeback.
Vermaelen’s return could see either Jan Vertonghen or Daniel Van Buyten drop to the bench, although Wilmots could very well stick with the team that impressed against USA in the round of 16.
Tottenham star Mousa Dembele is doubtful for Saturday’s game due to a thigh injury and Axel Witsel and Marouane Fellaini are consequently expected to continue their partnership in the midfield.
In attack, Wilmots will have to make a choice between Romelu Lukaku and Divock Origi as his starting striker, with the Chelsea man likely to return to the starting XI after his impressive performance off the bench against the USA.
