Cape Town - Mauricio Pochettino was left angry following his side's home defeat at the hands of West Bromwich Albion on Sunday.
West Bromwich Albion moved off the bottom of the table with a 1-0 win away to Tottenham Hotspur secured by Scotland international James Morrison's 74th-minute header.
The result was met with joy by traveling Baggies fans while the Spurs faithful booed their team off the pitch following a dismal display.
"I thought we played really well against a really good team," said Baggies boss Alan Irvine.
But disappointed Spurs boss Mauricio Pochettino added: "I think we had a very bad day. We need to be more alive and play quick. We made a big mistake on the set-piece."
"West Brom arrived here with only two points and last in the table but we need to show respect.
"We were wrong, we had a lack of movement. You need to be aggressive. We were wrong in this way. You need to show that you are the best team. The way we played, we brought risk into our game.
"So yes, I am angry. And disappointed. We had a bad day.
"The team looked very nervous in the game. The beginning of the game was wrong. We were slow, very slow tempo. You need to play quick. The way we played was wrong because we played very slow from the beginning."
Spurs sit in ninth spot on the English Premiership log, six points behind Chelsea.
It does not get easier for Pochettino as he takes his side to face Arsenal at the Emirates on Saturday, September 27.
