The FA Cup begins for the U's this weekend
The U's will be looking to beat a team from the league above them, but they've already beaten two Premier League teams in this season's Carabao Cup.
And the U's have arguably pulled off the biggest shock in the history of the FA Cup, when they beat Leeds United in 1971 when Leeds were considered the best team in the country, if not Europe.
Coventry City are the visitors to north Essex on Saturday for this season's First Round FA Cup tie, with the legacy of winning the cup previously.
They beat Tottenham Hotspur 3-2 after extra-time in 1987 to lift the FA Cup to become one of only forty two clubs to have won the competition.
U's Head Coach John McGreal has great memories of the FA Cup in general, and mentioned one of the Coventry goals as he spoke to the local press ahead of Saturday's clash.
"I remember when the FA Cup Final was an all day event in front of the TV. It was before Super Sunday was even a thought in anyone's mind, and started at about breakfast time.
"Obviously Liverpool beating Everton in finals was great but I also remember individual goals, including Ricky Villa's for Spurs against Man City, and Keith Houchen's diving header for Coventry."
"Coventry will be a tough test for us, but for clubs like ours, there's still a massive amount of magic about it because at the start of it you're always only two matches away from the big boys in the Third Round, and having a game like we've got in the Carabao Cup."
