Will Chelsea manager Thomas Tuchel use a back four or back five for the large majority of the upcoming 2022/23 Premier League? That is the golden question currently that not many supporters have the answer to.
Based on pre-season alone, the German has used both systems to experiment in the United States against the likes of Club America, Charlotte FC and Arsenal. Based off those three games alone, the back five seemed to give the Blues the most defensive stability.
This was evidenced by the most recent 4-0 mauling Tuchel's side took at the expense of their Premier League rivals Arsenal. In that affair, the makeshift back four made countless errors, some of which led to the goals themselves and chances that the Gunners spurned on the night.
