Romelu Lukaku reunited with plenty of former teammates as his Chelsea side headed to Old Trafford.
The Belgian, who was named on the bench, was seen shaking hands with several players in the tunnel as the two teams lined up before kick-off. Lukaku embraced Bruno Fernandes before the whistle blew whilst the likes of Marcus Rashford, David de Gea and Scott McTominay were all at United during his two-year spell and named in the starting XI.
Keane, who has been particularly scathing of his former side on several occasions, has previously slammed players who shake hands with players from the opposition before the game. The Irishman, who led United with huge success in the 1990s and early 2000s, was known for his intensity during his playing days.
