It is clear that the usual trio will fight for the championship, and so far there are no prerequisites for someone to wedged into this fight. But Barcelona and Ateltico are in crisis (and Real are on the rise) and if you can expect Atlético to be able to return to business (if only out of simple optimism), then Barcelona is unlikely, as financial problems bind it hand and foot.
I don't think Barcelona is in too much of a crisis. If Barcelona does not buy a new striker this season, they will not face any problems. Barcelona's forward Lineup is still strong enough. And their gameplay is excellent. Their only weakness is defence. On the other hand, if Real Madrid cannot add any new talented striker, and if Benzema cannot maintain his form, then Real Madrid's performance will be severely reduced.
