Aaron Wan-Bissaka believes Casemiro has added an elite mentality to the Manchester United squad and makes those around him "feel comfortable".
Brazilian midfielder Casemiro joined United for £60million last summer, penning a four-year deal with the Reds that will keep him in Manchester until at least 2026.
A five-time Champions League winner with Real Madrid, Casemiro's leadership and mentality has been at the core of this season's successes, with United ending their six-year trophy drought with Carabao Cup glory in February.
