If the respective tables are any guide then Dunedin Tech likely to be too strong for ChCh United and the same for Cavy over Western as Western still have a few injuries in their squad, and I think the Richmond vs. Coastal game maybe to close to call.
Another factor could be the refs as plenty of yellow and red cards handed out, with some of the player's hard done by. Hate to be a train spotter but also heaps of pens awarded, 15 out of 174 goals (8.6%) by far the highest since the MPL started in 2002, again from what I have seen some of the spot kicks have been very soft, i.e. outside the area.
With it being a full national draw in the next round there could be a few treasurers not that unhappy if their team losses over the weekend as the next round is set down for July 2 - 3, so not enough time to apply for Gaming Trust Funding.
