Tottenham manager Ange Postecoglou called his side's collapse against Brighton in the Premier League "probably the worst defeat since I've been here".
Spurs were 2-0 up after 37 minutes and heading for their sixth successive win in all competitions after goals from Brennan Johnson and James Maddison, but conceded three times in the second half as Brighton took the three points.
"It was disappointing and I’m absolutely gutted with that," said Postecoglou.
"It's an unacceptable second half - we were nowhere near where we should be. Maybe we got carried away with how we were going.
