I'd rather that, than have us learn nothing by playing 7-2-1. It was a 'men against boys' line up, and the result and the performance matched it - but he will (or should) have learned more about the players and the system, so no complaints on that.
No point in going through the recruitment changes that are needed, we all know what they are.
We absolutely need to be more aggressive without the ball in that system though. I felt the front 4 tried to press better but it's pointless if it's not backed up; we were bit 'between two stalls' really, but that's the whole point of using these games to blood in a new system. Make the mistakes while it doesn't matter, and figure out who fits.
Spurs played very well, which didn't help.
