The Chile international signed for the Red Devils in the January transfer window from Arsenal as part of the same deal which saw Henrikh Mkhitaryan head to The Emirates.
Sanchez has made something of a quiet start to life at Old Trafford despite having been a regular fixture in the first team at Manchester United since his move.
The 29-year-old, however, made a big impact on Saturday as he scored Manchester United’s equaliser and was voted as the man of the match in the Red Devils’ 2-1 FA Cup semi-final win over Tottenham at Wembley.
However, the forward has admitted that it has been anything but straightforward for him to adapt to life at the Old Trafford club.
Sanchez is quoted as saying by Goal: “In truth it’s been very hard for me, coming to a big club, it changed everything.
“So today I’m really happy, for the team, the goal and for the attitude we showed throughout the game.
“It was a great pass from Paul Pogba, and when the ball was in the air I wanted to hit it to the near post but then I saw the goalkeeper go the other way so I changed to the far post to catch him off balance.”
Sanchez could be set to line up against his former club when Manchester United take on Arsenal at Old Trafford in the Premier League next weekend.
The Red Devils are currently in second place in the Premier League table as they seek to try and finish as runners-up to Manchester City in the table.
