Arsenal attacker Leandro Trossard struggled in Belgium's 3-0 win against Sweden.
Romelu Lukaku hit a hat-trick to give Domenico Tedesco the perfect start as boss of the Red Devils.
But the win was not without incident as one of the Belgium players were singled out by Belgian media for an apparently poor performance.
Radio station RTBF reportedly branded Leandro Trossard, who started on the left flank before being subbed in the 61st minute, the "flop of the match".
The star was criticised for being "sometimes too low on the pitch, sometimes absent ... Trossard experienced a difficult evening."
They added of the 28-year-old: "He never really got his head above water. The author of dangerous ball loss shortly before half-time, he was substituted after an hour.
"We can rest assured: the Arsenal player has plenty of qualities, he will no doubt recover quickly. But this evening he will want to forget quickly."
