FA Cup Giant Killing: Where will the upsets come in the third round?

Chesterfield are the biggest outsiders in the upcoming FA Cup third round according to Betfair Exchange punters.

The scale of the task facing the non-league side, who play European champions Chelsea on Saturday evening, is represented by their massive match odds of 40.039/1 - the biggest of any team to win their tie from all 32 matches.

It was a similar story in the opening game of the third round where League Two side Swindon were 38.037/1 to pull off a massive upset by beating Premier League champions Manchester City on Friday night.

However, Covid has struck the City camp and Pep Guardiola's side have drifted to 1.241/4 for the win. Friday's hosts are in to 14.013/1 to pull off a shock win.

Elsewhere, Morecambe can be backed at a mighty 29.028/1 to emerge victorious from their Sunday afternoon visit to Spurs while a tiny element of doubt has crept into Liverpool's match odds, the Anfield side moving from 1.132/15 to 1.271/4 to beat Shrewsbury as Covid and the African Cup of Nations continues to cause major absences for Jurgen Klopp's side.

Eyebrows may be raised to see Newcastle among the list of heavy favourites - the Premier League's 19th placed club have won just one game in all competitions this season yet are 1.3130/100 to beat League One's Cambridge United. The visitors are a chunky 14.013/1 for the win.
