Them not having a conventional striker is both working against them and for them, there's an abundance of ball carriers who are technically extremely good.
Why would you say Liverpool, as a team, aren't tactically superior to United? You don't see a much better organised team, with better set pieces at both ends, quicker transitions, higher tempo, clearer purpose (and harder working)? I've been seeing that for 3 years now. Technically is a bit vague, if you're talking individual players, sure, we've got our own, but as a team what makes us technically on par? If you're talking about midfield, where they're weakest, they're still better. Technically as well.
