8月31日，當?shù)貢r間，在德國天空體育計劃中，馬圖斯談到了拜仁對青年訓(xùn)練球員的使用。

在德甲聯(lián)賽第二輪中，倫納德·卡爾（Leonard Carl）被安排在整個比賽的替補席上。

Mattus revealed: "I went down to see him after the game. He was very angry and upset that he had not been replaced. Normally, players could say, 'I am only 17 years old,' but he was eager to play. He was very fighting. There have been similar situations against Inter Milan. People criticized Kompani for relying on veterans, but he still always chose these older players, such as Boe, and they did not bring the expected performance."

馬圖斯說，這種情況已經(jīng)存在了多年：“我們必須將球員包括在一線隊的青年訓(xùn)練營中。這不僅要花數(shù)百萬歐元，而且更重要的是要從中受益。”

他強調(diào)，成功的青年訓(xùn)練系統(tǒng)最終應(yīng)該將球員交付給第一支球隊：“如果俱樂部擁有這樣的青年訓(xùn)練營，他們應(yīng)該在第一隊中充分利用這些資源。”
