Firstly, create a watchlist over in your profile. Next, when you're in the stats page, if you mouse over the word "manage" next to a player, it will pop up a bubble with all of your teams and watchlists in it- it's here that you add a player. If you're running a resolution of 1024 and find that the bubble goes off the edge of the page, you'll need to go back into your profile and click edit- in here you'll find a checkbox labelled Show TooSerious for a smaller resolution - tick this box and the bubble will now pop up to the right. Cheers mate.
