Kevin De Bruyne says that Roberto Martinez must adapt his tactics if Belgium are to have any impact at the World Cup finals next summer.
Belgium, quarter-finalists in Brazil in 2014, cruised through their qualifying group with nine wins and one draw but all is not well in the camp, according to the Manchester City star.
They drew 3-3 against Mexico in Brussels in their latest friendly outing but De Bruyne says the signs for next year's tournament in Russia are far from encouraging.
