I couldn't give a monkey's what 'boro have spent tbh. I don't think they have spent it to their best advantage anyway. (A view Karanka obviously shares.)
May the best team win.
With a 4-4-2 against a 4-5-1 you are going to have to accept that you will have a smaller share of possession and your front pair will have to drop in, "defend from the front" etc and you will be reliant on hitting your wide men quickly when you win the ball. I think this suits us best anyway...
