The 19-year-old, volleyed past Leeds keeper Karl Darlow in stoppage-time to deny the hosts victory and continue Bournemouth's impressive start to the season.

After six games the south coast club has 11 points – its best haul at this stage of a Premier League campaign.

Antoine Semenyo had put Bournemouth ahead with his fourth goal of the season, a thumping free-kick.

But Leeds hit back when Joe Rodon headed in from a corner swung over by Sean Longstaff and Longstaff volleyed his side ahead after the break.

It could not hold out, though, and French youngster Kroupi made his mark after coming on in the 81st minute, connecting cleanly with Marcos Senesi's flick.

Leeds is still unbeaten at home and is mid-table after six games with eight points.

"Of course [we are disappointed] because we had a really good game with a really good performance against a strong opponent," Leeds boss Daniel Farke said.

"We deserved to win this game. We had way more expected goals and shots. We had big chances."
