Roy Keane criticizes Casemiro’s performance during Brazil’s World Cup match against Japan, focusing on what he views as a poor first-half display. Multiple outlets report that Keane’s comments highlight Casemiro as struggling in the opening period, with Japan showing the sharper form early in the match. The criticisms are framed as a contrast to Casemiro’s previous standards, with one report describing the showing as that of a player not matching his former level.

At least one source adds that the match narrative changes after halftime, noting that Casemiro’s performance improves in the second period. While Keane’s main assessment centers on the first half, the overall reporting indicates the game’s momentum shifts as Brazil respond and the later stages become more competitive. The coverage portrays Keane’s verdict as direct and unsparing, but it is also situated within the context of a match where Brazil starts poorly and then finds a better rhythm later.
