This fella gets itHe does put the players under pressure, but it is a clear tactic used by Poch. If he goes short the opposition push up, but only the attacking front. The rest of the team cannot afford to push up. This then causes a massive gap between the opposition attack and midfield/defensive midfield. Ultimately leaving a spurs 7 vs opposition 7/8 making it easier to attack. I don't think this tactic should be used at 1-0/2-0 with 10 minutes to go however.
