I reckon the situation dictates the decisions. Villa is rubbish...play two out and out wingers...almost a 4-3-3.
Rom is not getting help...needs support. Bring on a striker who is best when he's supporting.
Good opponent...go with a more conservative defensive minded left side with Clev who offers Pienaaresque ability going forward.
The logic is really not hard to work out.
You mention logic and then you suggest Kone "supports the striker".
I mean, LOL.
