Offense doesn't win games all the time. There are times when you are doing so well on the offense that the match seems all wrapped up. Complacency sets in. The defending team is just bidding its time, waiting for the offensive team to slip up.
Wham! Its the 80th minute now and the score is tied at 2-2. Should the more offensive team try to score 1 more to win the game and risk losing the match even though a draw is suffice? Or should they just learn to start defending whatever they have since the more defensive team are in good form and high morale at this moment after coming back from two goals down?
Maybe you do need to learn a thing or two from Chelsea's manager Jose Mourinho - The Special One.
