Scare for Barcelona

Right now Barcelona and Sevilla are facing off in a very close soccer match. Right before the half Barcelona had a huge scare as the best player in the world (Lionel Messi) went down with a very painfull knee injury. Although they were up 1-0 at the half, with a goal by B.Krkic, Sevilla came back in the 49th minute with an amazing play and goal by J. Navas.  Will Messi's knee injury stop him from being amazin? Or will it give him and his team even more motivation?
