Motivate the team by helping your keeper warm up
When you're on the bench, you can still do your bit for the team by warming up with the keeper and helping them prepare for the match. You'll make sure they're in the right frame of mind. And you'll find the right words so they can get their head in the game.
You'll also encourage your team-mates as they warm up and get everyone pumped up and ready for the challenge ahead.
