The Red Devils manager has clashed on numerous occasions with his rival this season, but they appeared to be on cordial terms on Sunday
Jose Mourinho said his handshake with Antonio Conte after Manchester United's 2-1 win over Chelsea "did not need words" as the apparent truce between the pair continued after full-time.
Manchester United manager Mourinho has been engaged in a bitter war of words with Conte for much of the season, with their face-to-face meeting at Old Trafford long since anticipated as a result.
But neither man was willing to talk about their feud in the lead up to the game, which saw Romelu Lukaku and Jesse Lingard decide matters in United's favour after Willian had given Chelsea a first-half lead.
