Tottenham were beaten 2-0 by Liverpool at the Wanda Metropolitano in Madrid on Saturday.
Pochettino decided to drop semi-final hat-trick hero Lucas Moura in favour of Harry Kane, who had not played since picking up an ankle injury in the quarter-final with Manchester City.
Cascarino told talkSPORT’s Weekend Sports Breakfast that the Spurs boss got the big calls wrong for the final.
He said: “Kane, Winks and Trippier were three names I had written down yesterday morning.
“Kane, I just didn’t get it at all. Football is littered with some clubs, and internationally, that selected players who have been injured and I don’t like it.
“I think it is silly because you cannot prepare a player for a match, especially of this magnitude.
“I felt Poch really managed his team like a rookie manager.
“Poch got it wrong last night. It’s hard to criticise a guy who has done so brilliantly for a football club and like we chatted earlier about the finances of the club, being competitive, it has been exceptional.
