Thomas Tuchel's decision to omit Mateo Kovacic from the starting XI proved pivotal in Chelsea's 3-1 defeat to Real Madrid in the first leg of the Champions League quarter-final. The 27-year-old has enjoyed some dazzling displays this season but has started just four of his last nine games for the Blues.
Despite enjoying success with a three-man midfield against Los Blancos over two legs last season, the German boss opted for a pivot of Jorginho and N'Golo Kante on Wednesday night, although the latter made way for the Croatia international at half-time having been overrun by Carlo Ancelotti's star-studded midfield.
Toni Kroos, Luka Modric and Casemiro marshalled the centre of the pitch, uncovering an imbalance in Chelsea's tactical makeup. And, having learned from their mistakes, Real Madrid stagnated the supply into playmakers Mason Mount and Christian Pulisic.
