I find those who dismiss the importance of momentum in football, or indeed professional sport baffling. Whether it was distraction; attempting to avoid injury or deliberately trying to conserve energy in the Palace game, my view is that the weekend did have some consequences for PSG. We were not sharp and focussed for the first part of the PSG game, and it's very difficult to escape the feeling that had we used the Palace game as a primer for Tuesday's game this might not have happened. You could even turn it around and say that we were too wild (and therefore agitated) initially at the Emirates on Tuesday, having placed the emphasis on this, rather than the Palace game.
People point to the draws before the 2 Madrid games as somehow being evidence that league form has no effect on the CL, but for me this is trying to use an exception to prove a rule. Like I've said, you cannot turn professional performances on and off - it's a habit. At this level, the margins are super fine, and our preparation for Tuesday was not good. Dropping points to Palace has also affected our preparation for the return fixture - as our league position and even finishing in the CL places for next season is now considerably less secure, which makes Bournemouth almost a must win - given our remaining league games.
