Respectfully disagree.
Jones was in acres of space for his goal. Firmino was in lots of space when put through 1 on 1. We've not seen that recently at all. The box has been so crowded but with none of our players in there. Last night Jones was in there quite a bit. And Mane.
In the recent past Mane and Robbo haven't really combined to make a decent overlap or create space. Last night they weren't really trying to do that, and it almost gave Robbo more space with Mane moving inside and taking a man with him.
The beauty is that the systems can be played by all the same personnel, so when we become more adept, we can switch between the 2 which will further increase the problems on the defence.
Not time to get carried away, but it was what all of us have been crying out for (a change, any change in tactic) and it worked. The fact that we, with some practice could morph between the 2 is quite exciting imo.
