I suppose it boils down to how far you feel this manager can take us with his style of football.
For me I have never enjoyed counter attacking football. I find it too defensive and dreary and largely reliant on occasional moments of excitement.
Although there can be different iterations of the same overall style I believe in today’s environment success is more likely to be achieved by fast attacking football than by the passive variety.
For these reason I regard this appointment negatively and am largely unenthused.
I did not want a big name appointment just one that would play football I enjoy and I subjectively suppose would bring a greater chance of success.
For me, it's that you're reliant on the other side being better than you.
Counter attacking should be something you use in the odd game for pragmatic purposes. It shouldn't be Plan A.
