Aaron Lennon believes that Raheem Sterling answered his critics with an emphatic display for England against Spain. Sterling has shown excellent club form in the past 18 months. But many have questioned his England displays, as he failed to register a goal at the World Cup in Russia. But he produced a great all round display and got two goals in the 3-1 win over Spain. "He has been getting some unfair criticism," Lennon told Sky Sports News . "People have been on his case and I can't see why, because he has been brilliant. "He's a superstar for England and is so important for them, as he showed on Monday night. It was brilliant for him to score, I was really happy for him."
