Spierling played so well that Keinzley concedes he was left with no alternative but to start him against Napier City Rovers, the team Wairarapa United beat 2-1 in that memorable Chatham Cup final.
Not only did Spierling set up one of his team's three goals in their 3-3 draw with a well-timed through pass but his distribution skills in general were excellent and he was robust on defence.
"Aaron was outstanding. He did everything we wanted him to do and more," Keinzley said. "He simply had to be a first pick for this weekend, you couldn't leave him out."
The return of big defender Waisake Sabatu from suspension could, however, mean at least one change to the Wairarapa United starting XI on Saturday. His ability in the air and strength on the ball makes him difficult to overlook but if he is to play, then one of James Oxtoby, Pablo Moya or Shailer would be relegated to the bench. And with all three playing well against Olympic, that would be a tough decision.
Keinzley is anticipating a stern challenge from a Napier City Rovers team seeking revenge for their Chatham Cup loss, as well as redemption for a disappointing effort last weekend when they were beaten 3-2 by a Petone side down to nine players at the final whistle. Apparently their coach was also cooling his heels in the sin bin.
"They are a very good unit and last weekend will be a nightmare they will want to put behind them as quickly as possible," Keinzley said of Napier. "They won't lack motivation, that's for sure."
