The proof is in the pudding as they say. Ther current period is exactly why when you are 3-0 up you be ruthless and take every chance as if the score were 0-0. Arsenal would regularly thrash teams knocking in 4,5,6 goals.
Spurs, on the other hand, have often been lazy and simply blown easy chances. The mentality that it doesn't matter, we won anyway isn't the right one. It does matter. You train yourself and your brain to be ruthless, clinical so that runs like we are having now are minimised.
Prevention is better than cure. You don't wait until there is a problem before you cure it, you cure it before it occurs. Fortunately, we have a manager instilling the right mental traits into the players.
You learn from experiences and this young group of players are learning how to deal with the experience. Pochettino thinks it is important that they remain unbeaten, it adds another level of pressure to the opposition, as does the fact that we have set a new Premier League record the most time gone without conceding a goal from open play.
When you think of all the sides who have gone before that is quite an achievement. More wins would be nice, but we are only three points off the top spot so there is nothing to panic about.
