Martinez now faces a tricky decision concerning his line-up with Nacer Chadli and Marouane Fellaini pressing for starts after coming off the bench against Japan to turn the game around in the last half an hour.
"I am friends with him at the club but he is on his side and I am on mine, and I hope I can get the better of him".
The core of that side remains in place in Russian Federation, where Belgium has won all four of its matches, including coming back from 2-0 down to beat Japan in the round of 16 with a thrilling counterattack in the final seconds of injury time.
That 3-2 victory over Japan was the first time a team has overcome a two-goal deficit to win outright since West Germany beat England in 1970, and the first to do it in regulation since Portugal came from three down to beat North Korea in 1966.
Brazil will face Belgium in their Russian Federation 2018 World Cup quarter-final football match at the Kazan Arena in Kazan on July 6, 2018. But if we make this a match of individuals, then we'll lose. "The players that they have. both teams deserve to be facing each other a little further on in this tournament and not in the quarterfinal". "I will be doing everything possible to win, but we will continue to be friends".
Brazil are the favourites in what Belgium coach Roberto Martinez described as a "dream match" for his players when the two countries meet in a World Cup quarter-final in Kazan on Friday.
"The game against Japan gave us a big boost", he said.
De Gea's poor World Cup is ideal situation for Manchester United
Lee Grant will undergo a medical at Manchester United at Old Trafford later this week, according to Dharmesh Sheth. The Ivory Coast worldwide centre-back lost his first-team place towards the end of last season at Old Trafford.
"Everything is open, up for grabs", he said.
The victor will bid for a place in the final against either France or Uruguay.
If De Bruyne is able to exploit more space in Casemiro's absence, he will keep the lines of supply open to Lukaku, who is in prolific form, having already netted four goals in the tournament.
Neymar has two goals from four games so far in Russian Federation.
Though Brazil has yet to hit the heights on the attacking front, it and Uruguay have been the meanest defences in the competition, conceding just one goal apiece in four matches.
Manchester City's Fernandinho is likely to take his place, ensuring the Selecao retain an imposing platform in midfield.
The FIFA World Cup 2018 Brazil vs Belgium Quarter-Final match begins at 11:30 pm (IST).
Kompany evaded a question on how he would deal with any Neymar's antics, but said: "Honestly, I don't care". Others walking a tightrope are midfielder Philippe Coutinho and defender Filipe Luis.
