Tottenham Hotspur has received advice from the NFL American football league over plans for its new £400m ($517.5m/€459.5m) stadium.

Daniel Levy, the English Premier League football club's chairman, said the NFL has "contributed greatly in terms of knowledge and input" to the club's plans for its 61,000-seater arena, which is being built adjacent to its existing White Hart Lane home ground.

Tottenham's stadium is set to host a minimum of two NFL matches a season for 10 years following its completion in 2018, with a synthetic grass surface for American football stored underneath the pitch that will be used for football matches.

Speaking at a Tottenham Hotspur Supporters' Trust (THST) meeting, Levy insisted that the costs of hosting American Football will be offset by rental revenue from the NFL.

According to the ESPN sports news website, the minutes of the THST meeting read: "Daniel Levy confirmed that the NFL provision had not added much cost and would provide ongoing rental revenue.

"The NFL has also contributed greatly in terms of knowledge and input into enhancements to the stadium design and build and was a very valuable partner in that respect."

Levy added that the cost of construction has risen since the UK's decision to vote to leave the European Union in June. He said: "[Building] costs have risen as a result of the weakened pound, and the increased seven-day work schedule."
