New research has shown that the revenue gap between the top six clubs and the rest of the Premier League is now at an all-time high, although sizeable losses for two clubs almost single-handedly wiped out profit for the 'big six' in the course of a season.

Football finance website vysyble has produced a full revenue performance perspective for all of the Premier League last season, which has revealed that the top six clubs made more than £3bn combined for the first time in history.

The top six represents 58.25 per cent of all total Premier League revenue, which is up from 57.53 per cent the previous season.

Alongside this, the gap between the sixth and seventh clubs by revenue stands at £204.86m, up by almost £13m from the previous year

It represents a huge growth over the last decade, with the gap between sixth and seventh in 2008/09 being just £1.88m.

The big six also earned £1.38bn from TV rights, which is up from £1.22bn in 2017/18.

Yet the huge growth in revenue comes with a caveat - the combined pre-tax profit for the big six clubs was almost wiped out in a single season.

In figures that make for interesting reading, considering the stark financial future that football faces in the wake of the coronavirus, the big six's combined pre-tax profit in 2017/18 was £401.11m, yet, last season, this shrunk to a pre-tax profit of just £18.19m.

A large part of this was down to Chelsea and Arsenal both posting significant losses last season.

Liverpool's pre-tax profits were a healthy £41.9m, which was the second highest in the Premier League behind Tottenham Hotspur.

The Reds' financial figures were, like Spurs, helped by making the Champions League final.

In contrast, Chelsea and Arsenal's struggles perhaps underline the pressure on the big six to qualify for the Champions League.

Manchester United were the highest-earning club, with the gap between them and the lowest-earning club (Huddersfield Town) at its widest ever point of £507.8m - up almost £6m from the previous season.

In terms of the bottom end of the table, Fulham hold the record for the club with the largest-ever revenue total to be relegated.

Their £137.5m in revenue surpasses Stoke City's £127.9m the previous year.

The combined total revenue of the three relegated clubs last season exceeded £380m for the first time.

Overall, despite a combined £14.565bn in revenue over the course of the 2016-19 TV cycle, Premier League clubs have gone from making a £537.74m pre-tax profit in 2016/17 into a pre-tax loss of £169.98m last season.

This was largely due to the big six's profit being almost entirely wiped out.
