This is the only thing I can think of for being the reason to our woeful home form over the last 5 years. Players from other clubs who are used to playing at dumps like Accrington, morecambe and Exeter etc don't usually have the privilege of playing in a nice stadium and on a nice pitch on a weekly basis, so when ever teams come to meadow lane, they up there game as the place is like Wembley to what there used to.
Sheff united suffer with the same problem. I work with a Stoke fan and I was having this convo with him 2 weeks ago and he fully agreed to what I was saying as Stoke used to have the same problem about 12 years ago
