Nainggolan bows out after Belgium snub

MILAN - Roma midfielder Radja Nainggolan announced on Monday he was calling time on his international career after being overlooked for the Belgium World Cup squad.

The 30-year-old has played 30 times for his country, with his combative displays making him a fan favorite, but his relationship with coach Roberto Martinez has often been strained.

Spaniard Martinez flew out to Italy over the weekend to explain his choice.
