I don't agree with Blackwidow's notion that it happened because a key piece was missing in the squad, but it's definitely true that it wasn't on purpose. We played some lovely football from the start in the first half of last season, but we simply looked a step below in the 2nd half of last season in general. The team didn't play with the same determination, key players went missing, either through injuries or through a significant drop of form. The team always needed a kick in the ass at half time to get going. Add to it that Pep experimented too much with formations and tactics after the winter break and confused the team more than it helped and it all went wrong, especially after the league title was secured so early and we clearly lacked the determination we showed in the previous 18 months all of a sudden.
Wondering if VG can adopt the same strategy with us till the team is full in sync with his "philosophy".
I wouldn't read too much into our problems in comparison to van Gaal, who often stated in the past, that he wants to tire opponents and beat them with patience towards the end of games if necessary. So you could be right, that it is part of van Gaal's strategy until the team is playing in full sync. What was a problem for us, could be a temporary solution for you.
