If it weren't for Chelsea's downright abysmal away for home currently, you'd have to back them to easily overcome Cardiff. But because of that, you just get the feeling they will be put to the test by the plucky, route one favoring hosts. Cardiff aren't going to make it pretty for Chelsea, and you can expect them to invite the Blues' high press onto them. Whether they can exploit it is another question. In the end, the visitors should just about triumph.
