Similarly and for the same reasons, they have a lot of trouble combining the Spanish R with the Spanish G or J sound. Spanish words such as "jarra," "Jorge," or "rojo" tend to be very difficult even for Lusophones who are advanced Spanish speakers. But I agree that Portuguese is a lot more phonetically complex than most (if not all) Western European languages.
It gets even worse. Harvard Housing charges students "market rates" [0], i.e. they don't even subsidize what they are not paying in taxes off their own students' rent.
Yes, I'm getting there :) I speak French which is somewhat similar. However, I feel that what is difficult are not the conjugations per se but the irregularities. Each irregular verbs is a new conjugation table to learn!
