"I am amazed how much better he has got in the last month alone," says Dickie.
"He is getting sharper and I think he can improve again next season.
"It is exciting for us but also for trotting because Monbet is a very good horse and they already have a great rivalry and hopefully that can go on for a few years."
The pair are set to clash three more times this season, twice at Alexandra Park later next month and then in the season-ending Jewels at Cambridge on June 4.
Speeding Spur needed plenty of luck to win the final but co-trainer and driver Josh Dickie, on his 25th birthday, was ice cool.
"It was a great drive by Josh and we always believed he could win," said Dickie.
"It is my biggest thrill in racing and it's exciting to think about what might lie ahead for him."
