恐らく攻撃時には4231の様な形になってると思うよ。
下はクロップがバイチェチッチに関してのコメントだけど、8番だったけど、double sixつまりダブルボランチで多くの時間プレーしてたと答えるからね。

klopp on Stefan Bajcetic’s performance…

Pretty good... and we put him on a new position; you have to ask him actually, I don’t think he ever played the position before. He came here as a kid as a centre-half, played now the six for us in a few games and tonight as an eight and in a lot of moments a double-six, did extremely well. It was quite a good performance, to be honest

だから右のインサイドハーフならトップ下の選手が使われる可能性は高いんじゃないかな。
マウント来たら右のインサイドハーフが有力だろうな。
