Tottenham defender Eric Dier says his side 'lost their heads' as they tried to find a winner against 10-man Southampton on Tuesday.
Spurs had to settle for a point in a 1-1 draw after failing to break down the Saints, who had Mohammed Salisu sent off in the 39th minute for a foul which allowed Harry Kane to level from the spot after James Ward-Prowse's stunning opener.
Antonio Conte's men had two goals controversially disallowed by VAR in the second half, but they did not do enough to threaten overall.
