Real Madrid star Vinicius Jr. was on hand to praise Casemiro after the Brazilian returned to action with a typically dominant display against Barcelona on Thursday evening.
Casemiro enjoyed a break from his three-game domestic suspension to start in United's 2-2 Europa League first-leg draw at Camp Nou. Marcus Rashford's arrowed finish and an own-goal from Jules Kounde swiftly turned a one-goal deficit into a lead for the Reds, before Raphinha's cross curled past David de Gea to restore parity going into next week's Old Trafford meeting.
Midfield general Casemiro is two games into his domestic three-match ban, but made an instant return to the line-up in familiar territory in Catalonia. The 30-year-old had played 19 times against El Clasico rivals during his time in Madrid, and some of his former teammates were watching with vested interests.
