Casemiro was spotted barking instructions at Bruno Fernandes during Manchester United's 3-1 win against West Ham on Wednesday - despite tasting success just days earlier.
The Red Devils won their first trophy in six years last Sunday by beating Newcastle 2-0 at Wembley in the Carabao Cup final. Their celebrations were put on hold due to their FA Cup fixture against the Hammers three days later - a game they could have lost.
Said Benrahma's second-half goal gave the visitors a 1-0 lead at Old Trafford, but an own goal from Nayef Aguerd - plus strikes from Alejandro Garnacho and Fred - helped Erik ten Hag's side complete a comeback. Casemiro was at the heart of their revival.
