I agree 100% with the OP.
Giggs and Scholes still have valuable roles, but they should never start together, only play together if we're either winning easily or chasing a winner late in a game, and neither should start in a midfield 2 except maybe Scholes against absolute shite at home. And I mean absolute shite, even against lower-half PL teams it's dicey these days.
I also don't get why people are talking as if Carrick-Cleverley has been tried fifty times. Cleverley's still only played a handful of games alongside Carrick. I can't really see any reason why they shouldn't be able to play well together, and I don't get this post:

with a player who likes to bomb upfield and link with the forwards, a holding player who plays from deep is exactly what you want. It
avoids huge gaps in midfield. And Carrick may be no great athlete, but he's perfectly mobile, he covers a lot of ground.
The combination I always think could work if given more time is Carrick-Anderson. It's very balanced on paper - Carrick has the defensive positioning, the simple possession passing and the occasional creative long ball. Anderson has the energy and dynamism, can put a tackle in and also do the attacking link play, as well as having some good long passes himself. Of course, it would depend on Anderson being not shit for a decent stretch.
