Manchester United striker Romelu Lukaku has come under severe scrutiny due to his lacklustre run in front of goal. The Belgian who scored four goals in his first five games has currently not found the back of the net in his last 8 appearances. Manager Jose Mourinho admitted he has got striker problems, with Lukaku not in the best of form. Though he hopes the Belgian will find the back of the net soon and his confidence level will be back to normal. While Lukaku is on his longest barren run since leaving Everton for United in 2017, Alexis Sanchez is also struggling with an abductor injury. With his injury concerns, the Chilean played just 5 minutes against Chelsea, missed out against Juventus and looks unlikely to feature against Everton.
