Alexis Sanchez has taken aim at Manchester United ahead of their trip to The Emirates on Sunday by posting his support for Arsenal, despite previously playing for both clubs.
The Premier League title race could be blown wide open when United travel to take on the English top-flight leader's with the visitors looking to close the gap at the top to just five points.
However, Erik ten Hag's confident Reds won't be receiving any messages of support from former underachiever Sanchez, who has posted on his Instagram highlighting his love for the Gunners.
Re-sharing a video from Arsenal's account showing a Sanchez screamer he scored for the club against United during a 3-0 win in 2015, writing: 'You remembered me. I will never forget you too. You will always be in my heart.
'You were my first family in England and everyone took good care of me, especially the fans! All the best Gunners!!
Sanchez enjoyed an impressive three-and-a-half-year spell at Arsenal, scoring 80 goals in 166 appearances before being tempted to join Manchester United in 2018 in a deal that saw Henrik Mkhitaryan move in the other direction.
However, his tenure at Old Trafford failed to deliver on the performances he had been praised for at Arsenal with the winger struggling to find consistency or a regular place in the team.
Just five goals later and the 34-year-old was eventually sent out on loan in 2019 before making a permanent switch to Inter Milan.
His decision to leave North London for a Premier League rival at a time when many thought Sanchez was at his peak initially appeared to sour his relationship with Arsenal supporters.
But the former Barcelona star now appears to be trying his best to improve that relationship ahead of Sunday's crunch tie between two of his former teams.
Now at Ligue 1 side Marseille, Sanchez will be cheering on Mikel Arteta's side of Premier League title hopefuls, while a rejuvenated United side look for just their fifth league win at The Emirates in 15 years.
