Tottenham Hotspur manager Mauricio Pochettino said his team were arrogant and complacent after falling to a 2-1 Premier League defeat to Southampton on Saturday.
Pochettino could not hide his disappointment at his team's performance and told a post-match press conference he was concerned by the way his team let slip a 1-0 lead:
"I am so, so, so disappointed. I am a little bit worried about this change from the first half to the second half – it's only one thing, it's mental.
"It's about complacency, it's about arrogance in a bad way.
