Seriously, carrying a team for almost ten years in his back can't be that easy as it looks! he's been having a poor season, yeah you may agree with that, but he's not iron made.
I think he still has a lot to give not only to Liverpool but also to the national team, he just needs better players alongside him. Besides Stevie and Torres, we don't have world class players on the pitch so it gets a little complicated and Stevie (even if he sometimes looks like one) can't always be a superhero!
