Romelu Lukaku has had “a big change in his maturity” since joining Manchester United.
United signed Lukaku for £75million from Everton in the summer, and he scored his 20th and 21st goals of the season in the victory over Huddersfield.
Question marks remain over the Belgian however, with Chris Sutton particularly critical earlier this week.
But Belgium national team manager Roberto Martinez, who also oversaw the majority of Lukaku’s development at Everton, has praised the forward.
“Everyone looks at Romelu Lukaku and forgets that he’s 24,” Martinez said on Match of the Day.
“He’s already had two record transfers to Everton and then to Manchester United.
“I’ve seen a big change in his maturity. He’s got a little bit of everything. As a No 9 sometimes you play against them and they are a little bit predictable.
“He’s good with his back to goal, he’s getting stronger. With the space he’s unstoppable because he’s got that strength and power but his outstanding quality is his finishing.
“You get a good chance and he will score. He’s still a young player and is someone that can develop.”
