London Lions won the EuroCup final for the first time in their history after a dramatic second-leg clash against Besiktas at London's Copper Box Arena.

The Lions' 81-70 success saw them home 149-145 on aggregate after they narrowly lost the first leg in Turkey, making them the first British side to succeed at this level.

Holly Winterburn's three-pointer with 15 seconds of the final quarter left put the Lions ahead overall.

And the celebrations could begin when Megan Gustafson scored the final points as time ran out for Lions' Turkish opponents.

Karlie Samuelson led the Lions' individual scoring with 19 points, while Gustafson finished on 18.

"I'm so proud of us. We didn't come out how we needed to in the game in Turkey but we fought there, and that fight led us to this trophy," Samuelson told BBC Sport.

"When Holly took that shot I felt in my soul it was in; we're a really close team and everyone stepped up."

Lions had lost 75-68 in Turkey a week earlier, but led 45-35 at half-time in the return.

Besiktas closed the gap to five points by the end of the third quarter, but Lions made history in dramatic fashion.

"We deserved this, we've practiced hard every single day. The group has stuck together, I don't think I'll ever play in a team like this again," Winterburn told BBC Sport.

"With the funding situation, it's not an option [for me] to stay and I'm sad about that. I can't thank London enough for what they've done for me and British basketball."

Winterburn and GB captain Temi Fagbenle are among those likely to leave at the end of the season, with Lions unlikely to play in Europe next year due to a lack of funding.
