De Bruyne got the ball rolling with a fine finish early on, only for Timothy Castagne's own goal to level things up on neutral ground in Hungary.

But the Red Devils rallied after the break, with Belgium's captain scoring from the spot shortly after Youri Tielemans had restored its advantage.

Belgium took the lead in the 21st minute as Manchester City's Jeremy Doku skipped to the byline before finding his club team-mate De Bruyne, who finished emphatically.

Despite its dominance, Belgium was pegged back nine minutes before half-time as Anan Khalaili's header deflected off Castagne and beyond Koen Casteels.

But Tielemans restored the advantage three minutes after the restart, firing into the bottom corner after Lois Openda's neat touch.

De Bruyne grabbed his second of the game four minutes later after Openda was fouled by Raz Shlomo inside the box, finishing confidently from 12 yards.

Belgium was awarded another penalty soon after, with Openda again involved, only for the RB Leipzig striker to step up and see his spot-kick saved by Yoav Gerafi.

The Red Devils travel to Lyon next week to face France, which was beaten 3-1 by Italy in its opening fixture in Group A2.
