German or Italian??

I have a conditional offer to study Modern and Medieval Languages (MML) in October, which involves learning two languages (one of which can be studied ab initio.) I know that I will study French as my first language due to having studied it at A level, but I don't know whether to take up German or Italian as the second language. I like both of these languages, although I am marginally more intrigued by Italian culture and arts as opposed to that of German. Yet my concern is that it would be too easy to confuse Italian and French vocabulary and that the similarities between the two would actually slow down my learning of Italian instead of helping. Any advice on the pros and cons of learning Italian or German alongside French, and the importance of both languages in general? Is it worth learning German if a large majority of Germans are moderately proficient in English?
