PSG in the Champions League, can't say anything about their domestic competitions. But in the CL I just can't stop watching them. Win or lose, they play some lovely stuff, especially in the middle of the pitch. They're not afraid to pass it around under fierce pressure and stylistically it's fantastic. Napoli have been pretty good in recent years, especially this season. Liverpool and Dortmund can be enthralling to watch when they up the tempo against the big sides. And yes, Arsenal are usually pretty good to watch. The fact that they're usually harmless when it really matters makes it easier to stomach.
