This news medium understands that the 29-year-old midfielder decided to end his career with the Red Devils because United appeared not to be willing to keep him.
It was learned that Herrera felt irritated at the time it took the club to make an offer. This, according to reports, prompted him to ask for a wage in line with the club’s highest earners.
But the most successful club in the Premier League felt the player’s demand was too much.
And in an emotional video released on social media on Saturday, Herrera said “there is red in my heart”.
“Playing for the greatest club in England has been a true honour. Every time I represented this club, in every game, in wins and losses, even when I couldn’t help from the grass, I understood what this clubs means,” he added.
The midfielder, who joined the club under Louis van Gaal from Athletic Bilbao in 2014, is understood to have agreed terms with Paris St-Germain.
Herrera netted 20 goals in 189 appearances and won the FA Cup, League Cup and Europa League.
