Manchester United striker Romelu Lukaku missed training with the rest of Belgium's World Cup squad on Tuesday, two days ahead of the team's final group match against England.

Lukaku scored two goals in Belgium's 5-2 win over Tunisia on Saturday, becoming the first player to score multiple goals in consecutive World Cup games since Diego Maradona in 1986, but limped off just before the hour mark.

Lukaku said after the match in Moscow that he was "not too worried" about the prospect of missing the Group G decider in Kaliningrad, with Belgium manager Roberto Martinez admitting he could make wholesale changes now that the top two places in the group have been settled.

When asked about the possibility of changing all 10 of his outfield players against England, Martinez told reporters: "It could be an option. If I was going to speak about every player, I think everyone deserves to play in the World Cup.

"So, it's more important for me to be able to give that opportunity and see how they can react on the pitch and how much they can contribute. Nobody has got a place guaranteed in this team at the moment. That's the way we are looking at it. So, it could be a possibility do that, yes."

Lukaku's four goals so far in Russia put him one behind top scorer Harry Kane, but he told Belgian media on Monday that the Golden Boot is not something that motivates him.

"I restate that the title of top goalscorer doesn't interest me," he said. "My aim is to go as far as possible with this team. All the better if my goals can contribute to that."

"Maradona is one of the greatest players in history. It's nice. But he has won the World Cup. I've won nothing at all. I am keeping my feet on the ground. What I'm interested in is that the team wins."

"We're relaxed, but we have to improve our play game after game. We're nowhere yet. It's only in the second round that the tournament will start. We'll only be one of the favourites for the World Cup if we manage to produce such a performance against a big country. Let's not carried away.

"At the Euros, we had set the bar high, but we didn't meet expectations. This time, we're going to try and write history, especially for the boys of that generation who are going to retire."
