Instead, it was an all-too-familiar feeling for the departing Arsenal manager.
The Frenchman, who clinched the league and Cup double at Old Trafford in 2002, was centre stage before the game as he was presented with a gift by former United manager Alex Ferguson and Mourinho, and he was warmly applauded by the crowd.
'I think Fellaini will stay, ' the United boss said.
Though Marouane Fellaini's stoppage-time header secured victory for Jose Mourinho's side, there was much cause for optimism in the performance of an Arsenal side that was without a host of key starters ahead of Thursday's Europa League semi-final second leg at Atletico Madrid. "I turned many, many, many clubs down to face the challenge when we built the stadium", said Wenger, referring to the Emirates.
People are wondering who Arsenal will go for as their next manager but a more pertinent question is probably, who will want to succeed Arsene Wenger in the summer? "We were together a little bit before the game and I'm happy with the class my club showed towards him", he added. To say immediately change me is because he couldn't play.
A live screening of the match, organised jointly by the Manchester United Supporters Club Kerala (MUSCK) and the Arsenal Kerala Supporters Club (AKSC), will be held at ChaiCofi, a coffee shop near Kaloor, to mark the occasion.
The match saw Arsene Wenger visit Old Trafford for the final time as Gunners boss, with Mourinho paying tribute to a man he has shared many battles with in the past.
By then, United was 1-0 ahead thanks to Paul Pogba's 16th-minute goal.
Henrikh Mkhitaryan's goal against his old club looked to have earned a point for an inexperienced Arsenal side selected with Thursday's Europa League semi-final in mind, but Marouane Fellaini stepped off the bench to flick home a dramatic headed victor following Paul Pogba's opener.
Manchester City have put themselves on the map in recent years after dethroning United's reign in Manchester with three Premier League titles in seven years.
But Martial, who came off the bench for United late into the second half, wanted to make a personal acknowledgement of his compatriot's achievements.
