Other key players such as defenders Toby Alderweireld and Jan Vertonghen could also be rested, meaning they may miss the chance to go up against club teammate Harry Kane, and England coach Gareth Southgate is sending mixed messages over whether or not the striker, who has scored five goals so far in Russian Federation, will start.
But Martinez, who before the game had said winning was not a priority and made nine changes to his line-up, refused to look at the outcome that way and emphasised the vagaries of football.
"He said: 'Look, I know everyone says I want the Golden Boot".
It was so farcical at one point that Belgium's fans inside the Kaliningrad Stadium were cheering every time referee Damir Skomina brandished a yellow card to one of their players.
England were more slightly tapping than banging on the door for an equaliser at the end, cautiously optimistic that a loss on Thursday evening wasn't the worst thing in the world.
Prior to this tournament, Skomina also refereed the second leg of Liverpool's Champions League semi-final with Roma last month when he gave the Italians a late penalty in a 4-2 victory that was not enough to prevent Jurgen Klopp's men reaching the final.
Brazil v Costa Rica
Costa replaced Chelsea winger Willian at the start of the second period and there was immediately a greater urgency from Brazil . Thiago Silva admits he was "saddened" by Neymar's outburst at him during Brazil's 2-0 World Cup win over Costa Rica on Friday.
England ended the Belgium game without any injury concerns and so will have a fully-fit squad to unleash in the knockout stages.
Martinez has hailed the pleasure his whole squad have been taking on the pitch and has worked to build a team spirit whereas clashes of egos bedevilled the Belgians under his predecessor Marc Wilmots at the last World Cup and at Euro 2016.
Belgium started the better, Jordan Pickford looking nervous early on as he just about beat away a dipping Youri Tielemans effort.
"All those calculations weren't something for us but for the press".
English press divided The potentially easier route England was met with divided opinion in the British media.
Belgium, too, have made significant changes with Premier League stalwarts Eden Hazard and Romelu Lukaku all dropped to the bench. "But what that means for the next round, we don't really know", said Southgate.
Belgium beat England, 1-0, to win Group G and officially set the bracket for the knockout stage of the 2018 World Cup.
