seems tottenham Hotspur not want to participate in English Cup for concentrate on the premier league, I see this defeat is not reasonable because they playing is not like when beat liverpool.
most of big teams in england not to concern for english cup games because more likely they will concentrate their perfomance to the bigger competition such as EPL or champion league and i think it's natural if Tottenham more concern for these competition than play for english cup and that's why most of small teams will defeat big team
English Cup is not the main choice. Look at some big teams and even often play their young players to join this competition. Even the players who always become a reserve player even always be playing in the English cup. I think tottenham are a great team and they will concentrate on English league. Because each team will want to enter the top four in order to get a ticket to the league champions next season. I would bet that champions league is the most prestigious competition any team wants to compete.
