Belgium assistant coach Graeme Jones says Romelu Lukaku's development has accelerated since joining Manchester United.

Jones admits he is blown away by Lukaku's progress this season.

He said: “He's grown up and he's a real man now - he's a handful.

“In recent months, I've seen huge progress in his game and I've had huge personal satisfaction.

“His assists have improved, as has his back-to-goal play, his timing in the air, his use of his body, his use of his arms."
