You can see this with Arsenal. When Wenger first arrived they could beat you at football (Bergkamp, Overmars, Henry, Pires etc) but if the fluency wasn't there they also had the power and determination (Adams, Keown, Campbell, Vieira, Gilberto etc) to still grind out results. These days Arsenal are still formidable when the fluency is there (as we were in the autumn) but they don't have the resilience anymore if they are on the back foot. When Leicester got amongst us on Monday night, too few were up for the challenge.
