This is the definition of madness

How do you go in to the second leg of a home and home UP 3 GOALS (4 - 1), to a team from a lower division (Premier League top 18 teams, Championship next 24 teams), and almost blow it! If this was like the European-wide tournaments, Spurs would have lost on the away goals rule, 1 - 0 after 90 minutes of this game. They can't score for 118 minutes, but score twice in 2 minutes. Sheer madness!
