Tottenham Hotspur beat West Ham United 3-1 at the London Stadium with Son Heung-Min scoring in each half to book a place in the quarterfinals of the Carabao Cup.
Fernando Llorente wrapped up the win after Lucas Perez had pulled one back at the London Stadium.
The visitors made several changes after losing to Manchester City in the Premier League at Wembley 48 hours earlier but managed to carve out a two-goal lead through South Korean Son.
He put Spurs ahead after 16 minutes with a left-foot shot into the top corner from just inside the area after fine build-up play involving Christian Eriksen and Dele Alli.
England midfielder Alli provided the assist for the second goal but West Ham's Arthur Masuaku was at fault as he fluffed an attempt to block the pass, leaving Son to slot home in the 54th.
West Ham pulled a goal back with a header from substitute Perez but Tottenham's Spanish striker Llorente ended the contest with a fine close-range volley from a corner 15 minutes from time.
