Moura bagged a hat-trick in the semi-final against Ajax as Spurs produced a remarkable comeback to reach the final.
Boss Pochettino has gone for Harry Kane, who has spent a spell on the sidelines with an ankle injury, over Moura.
And Tottenham fans have been left raging.
One wrote: “Lucas Moura transfer request coming after the disrespect”
Another added: “So f***ing poch left out moura for Kane that just returned from injury. Isn’t this madness?”
And a third commented: “How the hell did Lucas not get a starting spot, I mean what ‘moura’ can he do”
A fellow fan wrote: “Lucas Moura has every right to give Pochettino a right hook”

Another posted: “Oh man you’d be fuming if you were Lucas Moura right now!”
With one other commenting: “Poch starting Kane in front of Moura is a bit weird. You’re in the final because of him ffs.”
There had been plenty of speculation over whether Kane would start tonight.
And pundit Ruud Gullit believes Liverpool will be PLEASED with Pochettino’s decision.
“He’s not in the best of shape, he can train but that is not match fitness,” Gullit said.
“So, for that reason, especially with the big guys at the back, you’d rather play against the big guy than a little guy like Lucas Moura.
“The pace of Moura, you don’t want that, so I think they’d rather have Kane.
“I think Liverpool are going to win it.
“It would be unbelievable if Tottenham win this, there have been games where they miraculously came back, but they have nothing to lose.”
