Option 2

In order to sabotage the other team, I would just sabotage lots of little things in order to inconvenience them for their pregame prep and game time rituals. First I would deflate their soccer ball so they can't play keep ups to warm up before the game, then I would tie their skates together in obnoxious ways so they would have to take time to undo them. I would also put clear tape over their blades so when they go to step onto the ice they slip and fall, I'd fill their sticks with water in order to add weight to them, I would also turn off their glove warmer in the warmup hallway so their gloves are cold, then spray some water into them so they are cold AND wet before they use them. Finally, the secret weapon is to get a bottle of bitters and put a drop or 2 in each water bottle, so the water tastes bad and they don't want to drink it on the bench.
