Belgium coach Roberto Martinez says he could recall in-form Roma midfielder Radja Nainggolan.

The midfielder was left out of the squad to face the Netherlands and Estonia in November.

“I didn't call him for the World Cup qualifiers with Bosnia and Gibraltar, but we scored two goals," Martinez told Humo.

“It's normal that you'd then continue with the same players. He played a half against Spain in September, and then a few minutes against Cyprus.

“The door remains open to everyone though, including Radja. I base my decisions on what I see, I have to be struck by a player to call him up.

“In November, he wasn't available for the Netherlands and Estonia."
