Tottenham are through, but the question remains: how good might they be if they ever decide to play both halves of a game of football.
Atrocious in the first-half, they rallied after half-time, equalised, hit the bar through Pierre-Emile Hojbjerg with nine minutes remaining, then scored a winning goal in the fourth minute of injury time when Harry Kane set free his captain again.
Yet should it really be this hard? Eintracht Frankfurt’s win in Lisbon looked to have pegged Tottenham in second place until the very last kick of Group D, which would have meant tougher tests in the round of 16.
