Casemiro's performances at the World Cup have drawn comparisons to his difficult spell at Manchester United under Erik ten Hag, but they also underscore the tactical acumen of current United boss Michael Carrick. The Brazilian midfielder scored a vital header against Japan in the round of 32, but his overall display has been marred by defensive lapses and a lack of support in midfield.
Casemiro's World Cup Woes
Against Morocco and Japan, Casemiro was caught out by fast, energetic midfield play. He was booked in both matches and substituted at half-time against Morocco. Against Japan, he was powerless to prevent Kaishu Sano's goal, dribbling past him before scoring. Roy Keane, analyzing the match for ITV, criticized Casemiro's positioning: "He's just getting bypassed every time the Japanese players get the ball. He's given the ball away three or four times, not under pressure. He seems all out of sorts."
Keane added: "His first movement has got to be backtracking to slow him up and protect the middle of the goal. Well deserved, very good strike, but from Brazil's midfield point of view, nowhere near good enough."
Carrick's Protective System
Despite playing in a similar 4-2-3-1 system under Carlo Ancelotti, Casemiro has been exposed. At Manchester United, Carrick devised a setup that hid Casemiro's weaknesses and maximized his strengths. The 44-year-old manager paired Casemiro with Kobbie Mainoo, whose energy and athleticism compensated for the Brazilian's lack of pace. United also ensured bodies were around Casemiro when opponents attacked, reducing his exposure.
Carrick's approach helped Casemiro recover from his poor form in the 2023/24 season. The midfielder's strong second half of the season at Old Trafford was a testament to Carrick's tactical adjustments. However, at the World Cup, those issues have resurfaced, highlighting Carrick's achievement in masking them.
Carrick's Rising Reputation
The World Cup has inadvertently boosted Carrick's stock. His ability to get the best out of Casemiro, despite the player's vulnerabilities, demonstrates his tactical intelligence. Casemiro officially leaves United today, but his World Cup struggles serve as a reminder of Carrick's successful management during his 17 games in charge last season.
