I watched that game as well. Agree, it was not a classic. I thought Aber defended well, considering they had 10 men. Llanelli missed some easy chances though. I agree Bala are more motivated. Llanelli have qualified for Europe for the last five seasons (I think), but Bala are showing the greater ambition as a club now.
Having thought about it, I'm actually going to bet on unders. 2.5 with William Hill. This represents a 40% chance, whilst Llanelli's games overall in the WPL have been 50% unders, and Bala's have been 45%. Add to this the fact that you'd expect it to be cautious, due to the importance of the occasion. Betting on unders in the WPL is a bit of a throw of the dice, as you never know when an error will gift someone a goal. But considering the stats I'm confident value is on unders.
