Opinions on this lineup

Like all these kinds of things it looks good on paper and a computer game but do the managers/coaches/players have the experience and nouse to make a formation work thats probably only been used regularly a handful of times in the history of football?

I'm assuming Olsson and Lowe would be wingbacks and would Rochina and Formica be wingers/strikers in the way that Duff and Robben were for Chelsea under Mourinho? Because otherwise you'd have a weird 2-2 centre midfield.

Your assumptions are correct.

Hmm well considering a lot of teams play 4-5-1 I think that 3 centre halves would be a bit overkill and could just encourage confusion. I think Pedersen would have to play ahead of Dunn or our midfield would be a bit too open. Not sure Formica can play wide right and Goodwillie and has seemed a bit lightweight as a lone striker. Who knows though, is there any particular reason for this question?
