Romelu Lukaku's goal drought extended to seven games when Manchester United were beaten 1-0 by Chelsea on Sunday afternoon.Spanish striker Alvaro Morata scored the only goal as Antonio Conte's side bounced back from the humiliating 3-0 defeat in Rome midweek.The 25-year-old former Real Madrid man produced a superb header to beat David De Gea early in the second half.Morata and Lukaku have each netted seven goals in the Premier League since making their big-money moves this summer.However, Manchester United's Belgian striker - who hasn't scored a goal in any competition since September - looks short on confidence.Lukaku had zero touches inside the Chelsea box on Sunday afternoon and he would be wise to watch the following clip from Match of the Day 2.The Premier Legaue's all-time record goalscorer Alan Shearer was on MOTD2 on Sunday night and had some words of advice for the former Chelsea and Everton frontman."When you're on a barren spell like he [Lukaku] is, forget everything about going out wide, about coming deep, thinking I'm not getting a touch of the ball," said Shearer."It's time to be selfish. Width of the 18-yard box, that's what he's got to think about. He isn’t going to score by running into corners."Let the people create the chances for you. He's a goal-scorer and he’s getting judged on scoring goals."He's going deep, he's going out wide. He's not helping himself and he's certainly not helping his team."It's not his job to go deep and create. Width of the 18-yard box, that's where he's most dangerous and that's where he's going to score goals."

If there's one man's advice Lukaku should be listening to - it's Alan Shearer.

The retired Blackburn and Newcastle striker - who now works as a pundit on the BBC - scored a whopping 260 Premier League goals.

Manchester United host Newcastle after the international break and Lukaku will surely be chomping at the bit, hoping to rediscover his remarkable early season goalscoring form.

Veteran striker Zlatan Ibrahimovic is reportedly hoping to return to first team action in December and Lukaku will be very much aware of the added pressure that will bring.
