What in the world lol? I will give you that they are comparable riders, but I think Lopez has proven himself significantly more times. He will absolutely be a GC rider and leader. There's no doubt in my mind that's what they are bringing him there for. There also is no evidence out there that any of this is about Valverde in any way shape or form. I don't buy into your assertions that every Movistar decision or move is ultimately about him, not a bit.
Straight from the horses mouth so to speak:
“Miguel Ángel López’s signing marks a really important addition to our men’s team. Having him aboard, we’ll not only enjoy the services of an experienced rider of great results, but also the style of racing from someone who always conceives this sport on the attack, trying to catch the rivals by surprise,” said Unzué. “He’s someone who knows well what it takes to step onto the podium of the Grand Tours, and who’s achieved important victories in one-week stage races. His addition to the team further bolsters our potential for the big tours in 2021.”

From Cyclingtips:
"At Movistar, López will join a handful of strong climbers hoping to usher in a new era of GC success for the team that saw Richard Carapaz, Nairo Quintana, and Mikel Landa all depart this season, while Alejandro Valverde is in the twilight years of his lengthy career.
Movistar will look to López and Enric Mas to lead the way for the team moving forward."
