Very few if any top coach would turn Barca down, it is the greatest club in the world and right now easily one of the top 4 or 5 teams in Europe. Why would anybody turn us down? No club is perfect and each has their own problems, Barca's problem is the board but they won't be here for long I would think. If a new coach comes in and does a great job then a new president would not get rid of them just for the sake of it.
So far Lucho has done ok, the second half is the most important one so lets see how he does. Maybe the constant rotations will help us in the long term and I don't think Real will keep up their current run of form for another 3 or 4 months. Remember Bayern hit bad form just at the wrong time last season and Real hit their best form at the right time. If we can hit our best form at the right time then we can win all 3 titles on offer. We topped our Champions league group, got through the cup very easily with youth players and are only 4 points behind Real who have gone on an unprecedented run of form so all in all not so bad.
Key to our success in Messi's form but also Iniesta, Pique, Busquets and Neymar. If we can get those 5 players at top form at the same time then we will beat any team and of course that will be extremely difficult but not unlikely.
