3-5-2, 3-3-2-2, or 3-4-1-2. We played a 3-5-2 against Motherwell, with Karlsson and Lazetic central, but we quickly shifted back to the 3-4-3 because the midfield struggled (that was the game that Armstrong looked knackered anyway). In my opinion, the 3-1-4-2, with Clarkson (or Polvara if we must) sitting in front of the defence, with two in front would work nicely. Similarly, two sitting, with Armstrong ahead would work fine too. I'd argue that none of these work particularly well with Karlsson in the side, but I find it bizarre that we haven't tried any of these options when looking for something to change a game, instead insisting that Nisbet comes on as a lone striker in abject failure, every single time.
