The Chilean and former Arsenal attacker has completed a transfer to Manchester United.
The deal saw Henrikh Mirkitaryan of Manchester united go the opposite direction.
The Chilean is expected to earn a sum of around 600,000 pounds a week making him the highest earner in British football, making him the 4th highest earner in football.
Alexis has been given the vacant an iconic no 7 jersey for the rest of the season.
In a statement, he heaped praises on the club saying am delighted to be at the best club in the world I have always wanted coming here throughout my career I spoke to sir Alex Ferguson but he didn’t seem interested in me, now I have the chance and I had to grab it.
Growing up I was a Manchester United fan.
Jose Mourinho has also given his delight for having the former Barcelona man in his team and he believes he will add more quality to his young attacking squad.
This ends the biggest January transfer saga news at least I can read something else in the football transfer news.
