The hitman has been struggling with an ankle injury but is now set to play for his country.

Lukaku has been in devastating form for Manchester United this season, netting 11 goals in just 10 appearances.

And when asked about the 24-year-old’s injury, Martinez explained: “Romelu Lukaku is fit.”

That news is a boost for United who will want their striker ready to face arch rivals Liverpool on Saturday.

But Jose Mourinho might prefer that Lukaku is left out of Belgium’s side to face Cyprus tomorrow night.

Marouane Fellaini has also suffered a knee injury on international duty but Martinez hasn’t spoken to the Special One.

He added: “We are in touch with Man Utd’s medical team.

“I haven’t received a phone call from Jose Mourinho as yet.”

Belgium have already secured their place at next summer’s World Cup in Russia.

United will go into their clash with Liverpool at 12.30pm on Saturday seven points clear of their rivals.
