You'll see in the API that if you pass an associative array to
FormHelper::select() it will use the keys as the option value and the
values (of the array) as the option content.

http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html#FormHelper::select

So what you need to do is format a new array from the data in
$players. Right now you have:

array(
array(
'Player' => array(
'id' => 'xxx',
'team' => 'something',
'number' => 'yyy'
),
etc.

You need to change that to:

$options = array(
'xxx' => 'Team: something Number: yyy',
'xxx' => 'Team: something Number: yyy',
etc.
);

You can do this with the Set or Hash utility classes, depending what
version of Cake you are using.

Then:

echo $this->Form->select('User.Player', $options);
