1) What is the lowest-ranked team to knock off a top-flight team at any level of the FA Cup? What level of the pyramid were they in? b) In the FourFourTwo magazine series on Marine FC a few years back, I caught a passing reference to their coach complaining that lower-division clubs like Marine could no longer host games involving upper-division teams. I'm assuming that grounds size and facilities are the reasons why, although I invite anyone to expound on this. My question here is: What is the lowest level that a team could be at to host a third-round match with a Premiership squad? Thank you for your answers.
