FA Cup 2021/22: Middlesbrough vs Chelsea – tactical analysis

The ambiguity of this current Chelsea side – which likewise speaks for much of the club’s success over the past twenty years – is that the more off-field chaos that ensues, the better and more formidable they seem to become.

Team notes and lineup

Chelsea’s hosts on a serene Saturday evening in North Yorkshire were certainly not there to merely make up the numbers – Middlesbrough had already knocked out Premier League titans in Manchester United and Tottenham in the two previous FA Cup rounds, and a festival pre-match atmosphere in the Riverside Stadium clearly suggested the home side fancied their chances of another upset. Wilder made no changes from Tuesday’s win away at Birmingham, deploying a disciplined 5-3-2 and hoping to replicate Chelsea’s curated wing-back system to stretch the visitors horizontally and battle them man-for-man.

Tuchel’s Chelsea in recent months have however demonstrated their ability to shake things up tactically, here deploying a 4-3-3 in possession and making five changes from Wednesday’s trip to Lille. Ruben Loftus-Cheek assumed a single pivot role in a three-man midfield that also subsumed Mateo Kovacic and Mason Mount. Christian Pulisic and the returning Hakim Ziyech flanked Romelu Lukaku upfront.
