Cristiano Ronaldo will be the man in the spotlight on Sunday, but Roberto Martinez says Belgium cannot afford to focus only on the Portugal star. 

Ronaldo tied Ali Daei's record of 109 international goals with a pair of penalties against France to send Portugal into the knockout stage of the European Championship. 

Still, Martinez insists Ronaldo will get no special attention in their last-16 clash. 

"When you put a plan against a specific player, you can be hurt by other players," the Belgium head coach told a news conference. "The way that Portugal plays, they’ve got a lot of threat, they’ve got a lot of pace in behind.

"Of course Cristiano Ronaldo seems to be the player that gets the right moment, the right pass and the right chance, and you have to be always aware, but you have to defend the 10 outfield players of Portugal in the same measure.

"We need to be compact, we need to be really solid, and we need to defend as a team.

"Obviously we always think about the opposition and that’s always the case, you need to have that information, but I think we’ve got real good momentum and that’s where we’re concentrating."

Belgium conceded only one goal across their three wins in the group stage, but their prime reason for optimism may rest in Kevin De Bruyne's successful return. 

After his swift recovery from facial fractures suffered in the Champions League final, the Manchester City star played nearly the entire game against Denmark after scoring in his return to action as a half-time substitute against Denmark. 

"Kevin, it’s been great to be able to see him 45 minutes and then almost the 90 minutes, so I feel that he is in the perfect physical condition to go into this game," Martinez said. 

"Kevin will have the normal role, an influential role. He’s not a player that needs to play in a certain position. We need to give him that opportunity to be the play-maker, to be able to link up to that possession that we have.

"We will have to be patient against a really good, resolute, and well-defensive-structured Portugal team, but I think we’re going to see ourselves doing what we always do."
