Lingard is a mid- or even bottom table player technically. He has average first touch, passing, shooting, and dribbling; he is bad at crossing. However, his physical (agility, acceleration), mental (composure, determination, self confidence, work rate, and teamwork) and tactical attributes are exceptionally good. Off the ball movement - world class.
I already mentioned in discussions that Ole is going to use a hybrid Lingard/Mata 10. Lingard - to tire down the opposition, Mata - to finish them off. Lingard is a big game player, his natural environment - pockets of space between lines. Deep sitting teams compress the space making Lingard look useless. We will have to use a more cunning player in Mata.
His role this season is much better defined, and the team tactics take into account his strengths, so I expect Lingard to do look much better.
