Luckily Barcelona is currently at the top of the La Liga standings so that Xavi's task is now having to make a strategy so that their defense is not easy to break and maintain its position at the top of the La Liga standings this season, the coach is able to bring Barcelona in a highly expected victory by all Barcelona players.
I think that xavi has no problem with barcelona's defense. As you can see that in the last match against madrid about how strong the defenders of barcelona kept its goal keeper from madrid's attack. barcelona is having some good defenders now. There's no thing that must be worry about barcelona's defensive. Xavi was even using parking bus strategy during the match against madrid in the first leg of copa del rey. The gap to the real madrid is too big to be chased by real madri.
Barcelona will face elche very soon. I expect it to be another easy match for barcelona. In another match, madrid must have faced valladolid. Barcelona and real madrid will get full points easily and nothing changed in the standing of la liga. La liga already in barcelona's hand. Barcelona needs to play the game and consistently winning it until there remaining matches will worth 12 points which are 4 matches.
