I never normally start a save with the Swans until I get my own tactic working well. I've now got a nice fun tactic which scores a massive amount of goals and doesn't concede as many as some of my other tactics I've made on FM15. It's a 2-3-2-3 (2 CB, 2WB, 1DM, 2AMC, 3ST). I'll fire up a save with the Swans and see how we go. I'll pick up a few wonderkids on the cheap. I'll let you know how I'm doing at Christmas.
I uploaded this Brendan Rodgers tactic a few years ago and it got good reviews. I can't get onto my old account now though which is a shame.
EDIT: A great start!
