For starters, maybe not just throw all the players forward whenever we have the ball and end up getting caught repeatedly on the counter, which happened a lot last season. Surely Lampard doesn't need a new coach to tell him that? The tactical fouling yesterday was good but we also did not just throw men forward. So we always, at least, had enough players behind the ball to deal with any counter attacks.
As a whole though, if we can build on what we did yesterday, then that would obviously be great but given we have been fooled or let down by many false dawns in recent years, I would wait for the next few games and see before forming any conclusion. After all, for example, we had games last season where we did everything right in one game and then couldn't even do the basics properly in the next one. So, yesterday was good but let's see after the international break.
