Belgium coach Roberto Martinez is delighted with the form of Manchester United striker Romelu Lukaku.

Martinez is also pleased with Chelsea ace Michy Batshuayi, who is now on-loan at Valencia.

"I have known Lukaku for a long time and I understand him," Martinez said when asked about Lukaku's form for Belgium.

"I knew his role with Belgium when I was at Everton - I just want him to score."

On the potential problem that Batshuayi could provide for Lukaku, Martinez continued: “I look at Batshuayi and see him putting pressure on Lukaku a little bit.

“[Lukaku] has to perform because Batshuayi is also strong."
