Well, they payed so much for them because they can´t negotate to save their own lives. God knows, why they payed 22 Mil. € for an one trick pony like Schürrle and while I actually rate Willian, he was nowhere near worth the 35 Mil € they payed Donetsk.
That is also not proper counter attacking football. That is building a wall around your box and hoping for a lucky punch. I can actually see an appeal in such a tactic, when it comes from a small club fighting for a draw, but a team like Chelsea, which threw 50 Mil. € direct investment on the market this season and has a 200 Mil.€ wage roll? For them it is just cowardly and disgraceful.
