Who is known as The Invincibles in English football?

In football, "The Invincibles" is a nickname used to refer to the Preston North End team of the 1888–89 season, managed by William Sudell,[1][2] and the Arsenal team of the 2003–04 season managed by Arsène Wenger. [3] Preston North End earned the nickname after completing an entire season undefeated in league and cup competition (27 games), while Arsenal were undefeated in the league (38 games) in a run that stretched to a record 49 games. The actual nickname of the Preston team was the "Old Invincibles" but both versions have been in use.
