This particular transfer announcement ranks as one of the worst due to hindsight, and nothing else. When Manchester United acquired the services of Alexis Sanchez in 2018, the Premier League was scared. As it should have been - the Chilean was arguably Arsenal's best player for a good three seasons, and there was no reason to suggest he would not succeed with the Red Devils.

However, watching it now, Sanchez's announcement video which consists of him playing "Glory Glory Man United" masterfully on the piano, and standing proudly in the middle of Old Trafford seems nothing short of hilarious. No one could have predicted the bad form of the former Gunner at Old Trafford, but there is something funny about the fact that the player's best performance in a Manchester United shirt came in the form of playing the piano during his Twitter announcement.

Although that tweet has gotten over 300,000 engagements on the social media app, no Manchester United fan is ever going to want to watch the clip again.
