BRUSSELS, June 12 -- Eden Hazard will be fully fit for the start of Belgium's World Cup campaign despite suffering an injury scare in the team's 4-1 friendly victory over Costa Rica, according to Red Devils coach Roberto Martinez.

The Chelsea attacking midfielder was replaced in the 70th minute of Monday's match in Brussels after receiving a dead leg.

"Eden is OK. He had a little trouble, but it's nothing to worry about," Martinez said. "At the end he just came off because he had a little bit of a dead leg, a little bit of a knock on his leg."

Hazard was named man of the match after a bright display that included an assist for one of Romelu Lukaku's two goals.

"I really enjoyed Eden's performance," Martinez added. "He was sharp and strong, he was majestic."

Belgium, third in FIFA's world rankings, will meet Panama in their opening World Cup match on June 18. They will also meet Tunisia and England in Group G of the tournament in Russia.
