The Man United striker is enjoying a fine scoring run for his country and the Spanish boss claims to understand how to get the front man firing
Roberto Martinez is confident he is bringing the best out of in-form forward Romelu Lukaku in a Belgium shirt.
The Manchester United frontman scored twice for his country in their Nations League opener on Tuesday, inspiring a comfortable 3-0 win in Iceland.
Lukaku has now scored 43 goals for his country, netting consistently under Martinez, and the former Everton boss is pleased to see the 25-year-old thriving, with Michy Batshuayi also in the mix.
