What if the choice is Lampard or no one? Lampard scored 12 goals this year. I know you credit Pirlo with the squad being the highest scoring squad in the league, but Lampard's goals had nothing to do with Pirlo.
I would argue that our tactics are entirely wrong and we are built for the counter attack. Hunker down and hit them long like Leicester City did last year. With Villa, Harrison and Shelton, we have the pace to still do that. Pirlo is good for a 50 yard ball to spring that, but he is a liability defensively.
