Rio Ferdinand has questioned Erik ten Hag's decision not to start Casemiro against Leicester at the King Power Stadium on Thursday night.
Manchester United signed the Brazil international, 30, from Real Madrid for an initial £60million last month. Casemiro is set to play a vital role in Ten Hag's side this season as midfield has arguably been United's weakest department in recent years.
Ten Hag was expected to deploy the five-time Champions League winner against the Foxes but decided to play Scott McTominay and Christian Eriksen in the heart of their midfield instead. Casemiro is fit after completing a full pre-season in the Spanish capital and made his United debut as a sub in the weekend win over Southampton.
