Dylan Bronn and captain Wahbi Khazri scored their consolation goals at the Spartak Stadium.
They had 23 shots, 12 on target, and Batshuayi should have scored a hat-trick after coming on for Hazard with 20 minutes to play.
"If we could have seven days to prepare (for) the game and then have another seven days until the next game, I would say let's carry on with the same starting 11", Martinez said. "We are a football team".
Or does he rest them for the last 16 and give players such as Danny Welbeck, Gary Cahill and Trent Alexander-Arnold a first run-out at the tournament? "There will be major changes against England".
He now sits level with Cristiano Ronaldo in the race for the "Golden Boot" in Russian Federation with four goals and he could have had even more if coach Roberto Martinez had not made a decision to substitute him with over half and hour still to play. A second yellow would see them miss the first knockout game.
Belgium has shown the most complete attacking force at the World Cup, though without yet playing a European or South American team.
"I always have to balance what's right for the squad as well. In front of goal he was as clinical as you might expect".
Harry Kane has said he is keen to get the chance to continue his prolific scoring form when England take on Belgium in Kaliningrad on Thursday with Gareth Southgate considering his team selection. The credit that we deserve is that we took those opportunities well. It's not every time you go through after two games, so we're happy with that. But while outscoring Panama and Tunisia 8-2, the defense and goalkeeper Thibaut Courtois looked like they could be exploited by better opposition.
England coach Southgate is unsure winning is an advantage: "We've got to think that through", he said when asked if he might field a weaker side against Belgium.
Tunisia lost their opening match against England but their supporters were confident that their team would secure a shock victory over Belgium, one of the tournament favorites.
"As expected, it was a very hard match", Maaloul said.
