BT has been criticised for the standard of its broadband infrastructure close to football grounds.
Gradwell Communications gathered upload and download data for the areas around each of the 92 football league stadiums to find which ones have a "title-winning internet" and who is in "danger of relegation".
League 1 side MK Dons were found to boast the highest connectivity speeds with an average of 179.6 Mbps, followed by Grimsby and Oxford United.
However, Premier League sides performed relatively poorly in the rankings, with just Everton and Bournemouth making it into the top 20 and six top-flight sides appearing in the list of the slowest 20 clubs.
Gradwell Communications believes it is "shocking" that Premier League stadiums are performing so poorly when it comes to broadband connections.
"While BT is spending billions on the rights to broadcast, it is still spending pennies on the broadband infrastructure around football stadiums," said Nick Thompson, Chief Executive of the company.
"Most football stadia are situated very close to homes so it’s even more troubling to see that the broadband speeds in and around some of the biggest clubs, not only in the UK, but the world are more like Conference North standard than Champions League."
Gradwell Communications figures showed that MK Dons' home ground Stadium MK is located in an area that has a broadband connection more than 14 times faster than the area surrounding the richest club in the world - Manchester United.
Interestingly, MK Dons boasted average speeds that were more than double any other club, helping League One claim the title of the fastest division overall.
By contrast, Manchester United came 64th in the overall rankings, while local rivals Manchester City lagged a further nine places behind.
Responding to the criticism, a BT spokesperson said: “We’ve invested more than £10billion into the Openreach network over the past decade – hardly pennies – and we’ve outlined ambitious plans to invest a further £6billion into our fixed and mobile networks over the next three years.
“Every football stadium in the UK can access a dedicated ultrafast service with speeds in excess of 1Gbps, whilst over 92 per cent of homes and businesses can access a superfast service.
”More than 19 million homes that could upgrade to fibre over our network today haven’t yet - so we’d recommend that people visit our online postcode checker to see what options are available to them.”
BT was recently ordered by Ofcom to legally separate from Openreach, so the infrastructure subsidiary is run as a distinct company with its own board..
