Social media exploded with fury as Villa fans took aim at the decision.
One supporter, @ctsmclovinya, fumed: "I don’t care if it’s Lionel Messi, giving a midfielder the number 9 shirt is a crime against everything football stands for."
@_Zeets said: "Number 9 as a midfielder? Enough is enough."
@wwfc2004 wrote bluntly: “Number 9 game is absolutely finished.”
@DOUGLASLUlZ was more forgiving but still baffled: “Don’t like the 9 choice, but this guy is so cold. Villa’s best ever RW? What a player, what a footballer. Him, Rogers and Sanch – straight vibes.”
And perhaps the sharpest jibe of the day came from @MoloneyBilly: "That should be illegal if you’re not a striker."
