Have you seen the complex role Rico's been asked to play? He starts as a RB, then inverts to a No 6, then in attack he's a No 8 & when the forwards need numbers to overload, he's a No 10.
If he's that far forward, it's not his job to be speedy Gonzalez & retreat to RB. That's the job of the right sided CB, whose central defensive position is supposed to be covered by the No 6.
When Rico (or Stones before him) gets back, it's at that point where he can resume his RB role. Rico's a footballer, not a triathlete on the marathon leg of his discipline.
Another crucial point you may have missed... When our inverted FB tactic led to wave after wave of victories & cup & title success, the world & his best mate adopted the inverted FB tactic, including Klopp with the Dippers & waistcoat for England. How many teams are still doing it today?
Look at Spuds yesterday. They played a 5-4-1 in defence & in transition they poured forward into the spaces we vacated & punished us. The warning signals were there against Wolves, however they didn't have the individual player quality to capitalise.
I said last week that if Wolves had better quality, they should've scored 3 against us. Against Spuds, their better quality in defence, transition & attack told, & since our mid-season collapse last November, this is yet another top team who we've failed to beat using our inverted FB system.
Little of this is Rico's fault. Our tactics have been sussed, but yet we persist. Pep Guardiola decides our formation & tactics, NOT Rico Lewis...
