Las Palmas done extremely well , they made it so easy against Valencia and Granada. But i know it isn't enough to prove since they haven't face Real Madrid and Barcelona. i think they will be fine if they keep getting from the average teams , they have the potential to stay at least in the top 6 for europe game.
Kevin Prince Boateng is a really good signing from them. After a few bad seasons he had suffer , i think he should be eventually shine again and Las Palmas is the first step.
