Belgium have handed Club Bruges defender Brandon Mecehel a first call-up and recalled three others as coach Roberto Martinez hopes to use this month's internationals against Switzerland and the Netherlands to bring new players into the squad.
Mecehel was a surprise choice in the squad Martinez named on Friday when he also recalled Jason Denayer, Christian Kabasele and Dennis Praet.
Injuries to the Tottenham Hotspur pair of Moussa Dembele and Jan Vertonghen plus Kevin De Bruyne (Manchester City) and Adnan Januzaj (Real Sociedad) have allowed Martinez the opportunity for some experimentation, he said at a news conference.
Belgium, who are now top of the FIFA rankings despite finishing third at the World Cup in July, host Switzerland in Brussels on Friday, October 12 in the Nations League and then the Dutch in a friendly on October 16.
