Cape Town - Harry Kane jokingly offered his services to the NFL after skiing his penalty against Southampton before admitting he saw a "new patch of grass just on the penalty spot" but still failed to convert.
The England international stepped up to the penalty mark in the 58th minute of Tottenham's 4-1 win over the Saints at St Mary's on Wednesday, having netted just six minutes earlier from open play.
With Spurs narrowly leading 2-1 at the time - having come from a goal down after just 60 seconds from Virgil van Dijk - a successfully converted kick would have put the Londoners out of sight, but Kane slipped on the pitch and fired his effort high over Fraser Forster in goal.
As it was, Deli Alli, who netted Spurs' first, and Heung-Min Son went on to score two more goals, with Kane afterwards admitting his miss was poor.
He told Sky Sports: "The ground just gave way under me. I saw it before the game. There was a new patch of grass just on the penalty spot.
"It's even more devastating that the keeper went the wrong way as well. I'll be thinking about that one tonight."
He posted on Twitter: "If there's any @NFL teams looking for a kicker in the future, have a look at my game tonight! #SOUTOT"
Kane was, however, happy to have scored earlier in the tie after going the previous three games without a goal.
He added: "Whenever I go one or two games without scoring it seems to be a big deal. It shows where I'm at and the position I'm in.
"But I just try to help my team and score goals for the team and I was thankful to do that today."
