While Lingard undoubtedly has an alarmingly juvenile personality, and an extraordinarily punchable face - he is a better player than people give him credit for. I like him as a squad player. His movement IS good, as is his workrate. And he has moments of excellent quality on the ball. Especially running at tired defences.
Ultimately he is not consistent enough to ever be a top player, and he should never be considered a starter for us. But again, the season is long and you need decent, dedicated players to get you through the plethora of games - including the EL. Jessie is ideal for that.
