But you have to think England will eventually need to contend with a side that's not going to concede from set pieces. The Chelsea man will also be facing off against Eden Hazard, and will certainly be looking to get one over his team-mate at club level.
Martinez's team tackles the 1998 World Cup winners in St Petersburg on Tuesday for a place in the final, marking the first time Belgium have reached this stage of the World Cup since 1986, when they finished fourth.
But their secret weapon could be on the sidelines in the shape of one of France´s greatest players of all time, Thierry Henry, who is now head coach Roberto Martinez´s assistant. "He will be with the Belgians and do everything to help his team".
Belgium´s Kevin De Bruyne said Henry had talked little about his feelings. While Hazard and De Bruyne will largely have free roles in the final third, Lukaku will look to stretch the defensive line in order to create space for his attacking partners to exploit and possibly find scoring opportunities. "It is a hard situation, it really is not easy for him".

The 23-man Belgium squad has 12 players who play in the Premier League, a competition which Kante has dominated to such an extent that he has now won two league titles in his three-year stay in the division.
Mbappe was lethal in France's 4-3 Round of 16 win over Argentina, using his pace to devastating effect, but Martinez said his side would not make the mistake of focusing exclusively on one player.
The victory boosted France's morale, and they followed it up with a workman-like 2-0 win over Uruguay that was impressive because of how well they managed to control the game against tricky opponents.
They also lost the 2006 final to Italy on penalties, though experience won't be a factor given that not a single player left in the tournament has ever reached the showpiece before. It's one shot at the final, no second chances!
"He's brought something we didn't have", said Spanish coach Martinez.
A key talking point ahead of tomorrow morning's (Singapore time) World Cup semi-final between Belgium and France has been which country's star player will shine brightest. For him this game could be hard but he is working for us now and he wants us to win.
"Belgium played a great game against Brazil with a specific game plan". Harry Maguire's brilliant aerial performances so far this tournament, culminating in him winning 22 headers against Sweden and Colombia, would suggest Jordan Pickford's goal won't be regularly troubled.
While Antoine Griezmann and Kylian Mbappe top France's scoring charts with three strikes each, Lukaku has hit the back of the net four times for the Belgians.
"This time, in an worldwide match, it is much higher".
France, world champions in 1998, are slight favourites to go through according to most bookmakers, but Belgium tend to step up their game against these particular European rivals, if history is anything to go by.
From 32 nations at the World Cup, four remain.
Goalkeeper Danijel Subasic and right-back Sime Vrsaljko, who both picked up an injury against Russian Federation, and centre-back Dejan Lovren were all absent from the part of the session open to media.
Defender Domagoj Vida escaped with just a warning from Federation Internationale de Football Association, which bans political statements, for also appearing in the video and shouting "Glory to Ukraine!"
