It's December, and we are talking about Jesse Lingard, not Eden Hazard, when he does not score, he barely contributes anything other than backward passing and pressing the goalkeeper. Never mind, let's agree to disagree on his contribution. And since you mention his World Cup performances which have nothing to do with United, Lukaku had a solid World Cup also.
I was just referring that when everyone is fit our best attackers should be given chance to establish themselves back in the team, because it would make us a better side.
