Belgium boss Roberto Martinez doesn't understand why Romelu Lukaku is treated badly when Manchester United fail to score.
The 25-year-old has scored 28 goals in 26 international games under Martinez while the Belgian striker's tally is six in 22 appearances for the Red Devils this campaign.
Lukaku has netted 61 goals in 126 appearances under the former Everton boss and Martinez doesn't think the United forward should take the blame.
'There is a negative way of assessing Romelu's performance for Manchester United, ' the Belgium boss told The Sunday Times.
'When Rom scores everyone expects him to score and when he doesn't he is almost directly the reason United haven't won.
'But Rom is ready for that challenge. He will never hide away. He understands what is expected of him.
'For Belgium he has shown he's one of the best No 9s in the world and I don't understand why he's being treated in a manner which he doesn't deserve.'
The Red Devils beat Cardiff 5-1 without Lukaku, who is on compassionate leave, in Ole Gunnar Solskjaer's first game in charge.
The Belgian star is unlikely to return before the end of the month.
