I agree with the bit I highlighted. Ranieri isn't bold, Wenger isn't bold anymore. Peligrini isn't bold. A tactical mastermind, & outstanding player recruitment is great but getting a team to be a unit is vital to consistency required for a top 4 finish- hell an organised, well drilled, PED-fueled Leicester won the big one last year. Once team spirit was gone, they've become a sack of spuds.
I think Koeman is certainly ambitious, but whether he's good enough with attacking coaching to make us an elite team- I don't know. Guess if we get the top bracket players we will find out!
