Playing a high tempo, pressing game for 90 minutes plus added time can be hugely successful, especially in the lower leagues where players are more prone to make mistakes when put under pressure. The big challenge though is that it does require a huge level of fitness from the players, and intelligent use of substitutions to ensure the most fatigued players are replaced in a timely manner.
Whilst it can be successful (as we saw in the first half of the match), unless you have a team of super fit athletes it is almost impossible to play like that for the whole match (as we saw in the second half). To add to that, the cumulative fatigue of playing in such a way week after week will likely lead to a huge slump in performance after a month or so.
If you are to play a pressing / high tempo tactic match after match you will need a big squad of fit athletes so you can rotate them to keep the all fresh. And this is the challenge for us.
