Both sides have identical records for their last eight games - W5 D2 L1. Earlier league results between sides in the playoffs don't seem to give any indications of the playoff result, so Boston's wins home and away against York don't help! The attendance for the playoff match at York against Chorley was a massive 6,394 with only 314 away supporters. Boston should bring a few more. So I'm going for:
York City 1-1 Boston United (7486)
It's the score at the end of normal time that's being predicted.
