Wasn't Mallorca partly because of players not being paid?
According to wikipedia: "Laudrup resigned from his job, following the firing of his assistant, Erik Larsen. Laudrup cited that great frustration with Lorenzo Serra Ferrer, the club's Director of Football, leading to a bad work climate as the main reason for his resignation". So probably a mixture of many things.
I still don't think it was a good idea, firing Laudrup. Only two points above the relegation zone and how will all the Spanish players react to the firing? Monk taking over, who was fighting with Chico Flores at a training not that long ago. I think they will go down this season.
