Mauricio Pellegrino’s men were dealt a disappointing Boxing Day blow by in-form Spurs, who netted on five occasions, while Saints could only find reply twice.
Sofiane Boufal and Dušan Tadić were on the scoresheet, but stealing the headlines was 24-year-old Harry Kane, whose eighth hat-trick of 2017 broke another string of Premier League records.
The Southampton manager noted the opposition's attacking talent on display at Wembley today, after conceding five, and further asserted that his team will need to exercise ‘togetherness’ in order to overcome a difficult stretch of results.
“When we concede the third goal it was really difficult to come back,” the manager began. “I think we reacted well in the second half, to try to score goals and be in the game.
“Obviously our goals came late, but we pressed higher and tried to show what we are [capable of]. It was important to show some character in those moments.
“Sometimes the difficult moments are useful for seeing how people will react. Our profession and our life in football is made from these moments, the difficult times help the team to be together and be stronger. Hopefully we can bounce back from this moment.
“Against the top teams, you cannot make any mistakes, because they don't make too many. Some amazing players today, a lot of quality up front, allowed them to score goals with few chances. It is the level of the Premier League.”
