Tottenham Hotspur manager Mauricio Pochettino has backed striker Son Heung-min to step up in the absence of Premier League joint-top scorer Harry Kane
Kane is likely to be sidelined with an ankle injury for most of the remainder of the season.
The England international left the field just 10 minutes into a 6-0 FA Cup thrashing of Millwall on Sunday and had to exit White Hart Lane in a protective boot and on crutches.
But a hat-trick from Son and goals from midfielder Christian Eriksen, Dele Alli and striker Vincent Janssen ensured Spurs' progress to the semi-finals.
