Recalled by Carlo Ancelotti, Casemiro became an untouchable figure for Brazil — until a disappointing World Cup start made him a prime target for criticism at home.

The former Real Madrid player, one of the leaders of the squad chasing a sixth world title, looked destined to anchor Brazil's midfield at the tournament after an impressive final season with Manchester United. But his limp display in Saturday's 1-1 draw with Morocco, in which he was replaced at half-time, has left the 34-year-old enduring his lowest moment since first pulling on the famous yellow shirt in 2011.

The performance has also strained the bond between Brazilian fans and Ancelotti, hailed as the man who could lead the five-time champions back to the summit for the first time since 2002.

In his first squad selection, Ancelotti surprised many by recalling Casemiro, a five-time Champions League winner with Madrid during a nine-year spell in Spain. The holding midfielder had been out of the Brazil picture for more than 18 months, but Ancelotti revived his international career, starting him in 12 of the 13 matches he has overseen.
