Italian football rollercoaster

AC Milan doing one of its great seasons in the Serie A, leading with 5 points difference over Inter Milan, and just had a great 1-0 victory vs. Juventus. Milan looked very paled and helpless vs. Tottenham Hotspurs, which didn't play its best games yesterday.
Tottenham itself had sensational 3-1 victory over Inter Milan few weeks ago, now knocked out AC Milan 1-0 for two aggregate games.
