Fairlop boss Aaron Dias praised defenders Daryl Rubin and Max Gold for snuffing out the threat of Bayern's 30-plus goal striker Adam Ellis.
Explaining his approach to the game, Dias told JC Sport: "I challenged the boys to start fast and boy did they! We knew that if we pressed high and played our attacking, sexy football, early Mincha wouldn't be able to handle us and that's exactly what happened.
"We scored three goals in quick succession and the game was won. A few Mincha heads were lost, notably their captain who should have been shown a red card for a disgusting two-footed challenge on Adam Goldman.
"The first half unfortunately had 15 minutes added on due to a nasty head injury to Bradley Porter, who I am happy to confirm is fine after a visit to A&E and a four stitches.
"We should have had more goals in the second half, but overall delighted with our performance in such a big title deciding match.
"It was a big step towards the title but we know there is still a lot of work left, with us need to get 10 points from our last five games."
Vale joint-manager Jacob Emanuel told JC Sport: "It was a shame to end the season like that. However, we were far from our best today and Fairlop capitalised on that. They were the better team and they won deservedly.
"We knew they're a talented bunch and knew it wasn't going to be an easy test.
"Our chances of winning the league are now extremely thin as we can only rely on Fairlop losing. However, our target of getting promoted - that we set at the beginning of the season - was reached.
"We have had a great season and I'm extremely proud of all the boys. We are very much looking forwards to next season."
