Former Floriana coach Luis Oliveira is disappointed that Radja Nainggolan was not considered by Belgium's coach Roberto Martinez for the 2018 FIFA World Cup.
"I am sad that my friend Radja Nainggolan was not called up to play part in this Summer's World Cup," said the former Belgium international to timesofmalta.com.
Nonetheless, Oliveira still tips Belgium as one of the potential candidates to do well in this tournament given the talent the squad boasts.
"I do think that this national can have its say in this tournament because there is a lot of talent, including Dries Mertens and Kevin De Bruyne who can make the difference for Belgium," the former Cagliari and Fiorentina forward underlined.
