Alexis Sanchez is reportedly fuming with manager Jose Mourinho's decision to leave him out of Manchester United's 18-man squad to face West Ham United.
The Chilean forward was dropped for Saturday's clash at the London Stadium, which the Red Devils lost 3-1 to prolong their poor start to the season.
According to The Mirror, the 29-year-old was left stunned by his exclusion as he was part of United's travelling party, only to be informed on the day of the game that he would not be involved.
Sanchez, who has yet to net in the Premier League this term, is said to have made it clear to everyone behind the scenes that he was unhappy with Mourinho's decision.
The report indicates that the January signing from Arsenal - allegedly the English top flight's best-paid player on £350,000 a week - is already regretting his move between clubs.
