Manchester United's rivalry with Arsenal between the late 1990s and early 2000s was inarguably the most iconic the Premier League has ever seen.
There were very few handshakes, hugs and shirt swaps, they were instead replaced by square-ups, shoving and bone-crunching tackles. Amid all that, of course, there was some sensational football between two teams battling it out for Premier League titles and given what was on the line, it is understandable that tempers tended to flare up.
One of United's key figures from that time, Ryan Giggs, has previously admitted that the bad blood on show was authentic and openly confessed there were four Arsenal players he disliked more than most.
