When Plymouth beat Rotherham in April it was an important game for Argyle because it kept their play-off hopes alive.
But for Zak Vyner, he was using it as an audition.
The 21-year-old was on loan at Plymouth from Bristol City and was enhancing his growing reputation.
There had been a chance of coming to the AESSEAL New York Stadium instead of Home Park and discussions of the season-long loan to the Millers he finalised on Monday were in an early stage.
That meant Aryle’s 2-1 win over Paul Warne’s men took on extra significance.
“I played against Rotherham last season, it wasn’t the best result!” he said. “It was a good test to see what they were going to be like, I knew there was a bit of interest before I went to Plymouth so I knew it was a big test for me then.
“ It was a good game, they showed they were a good side, they were pressing me 24/7.”
Vyner trained with his new Millers team-mates for the first time on Monday.
This time next week he may be on his fourth hill run of the day in the Austrian Alps and he is fearing the worst.
“I am going into it completely blind but I know the gaffer is a fitness fanatic so it will be interesting,” he added.
“I have heard about the hills in Austria!”
