Messi thinks the La Liga title his side has just won should be valued while admitting that they missed their coach Tito Vilanova."I think it is a very important title due to what the Spanish League means and the rivals that we have, such as Real Madrid for example which is one of the best sidesin the world", he said in an interview on Azteca Television. "We were on the back of a change when Guardiola left so when Tito took over it was really good for us until he then had to leave and we noticed the change.It was not because Roura or the others were not up to the job, it was just that we lacked our first team coach who had spoken to us and transmitted to us his own messages from day one and it was obviously not the same without him", he said.Messi thinks that despite the defeat to Bayern, his side should persevere with its style of play. "It gets more and more difficult; you can’t win everything every year.We have been playing the same way for a long time and all the coaches and opponents study the best way to stop us winning, but we can’t lose our heads over what has happened to us this season. We can’t change the Barcelona style of play that has always characterised this side. We have to be calm now and think about next season", he continued.With regards his own future Messi said: "I’ve said it many times: one day I would like to play in Argentina, but today I am only thinking about staying here until the very end".
