Manchester United are currently in the middle of their longest unbeaten run, since Sir Alex Ferguson retired in 2013.
Monday’s 2-0 win at West Ham, made it 13 games since their last defeat.
Jose Mourinho’s men have not lost since Fenerbahce beat them 2-1 in the Europa League on November 3. They have gone on to win seven games in succession.
The Red Devils went 18 matches unbeaten in Ferguson’s final season, when they won the Premier League title.
Ferguson’s successor, David Moyes, also oversaw a 12-game unbeaten run in the 2013/2014 season, while Louis van Gaal’s United side went 11 games unbeaten in the 2014/2015 campaign.
