I'm not sure it's such a bad thing as far as Jurgen is concerned. His teams tend to play with 3 men behind the striker but the 'outside' players don't play as wide as wingers; they play narrow, compact and do a lot of quick 1-2s and through balls, so maybe we'll be able to utilise all of our number 10s after all.
His Dortmund team did play with 3 behind one striker but when they were at their best Reus was on the left and Blasczykowski was on the right. Gotze was then in the middle behind Lewandowski.
The big difference between this and our squad is a serious lack of pace, both Reus and Blasczykowski were quick which meant they could play wide if needed. We have nobody who could do their jobs from what I can see, Firmino maybe in time?
Coutinho could play the Gotze role but were short in the other areas for me.
