I agree with both of you, but I was thinking more off purely on both of them, Pedro is someone who excells more in running into channels and realying on creativity of others more (more so now, he looks half the player he was after injury), then Valencia who isnt a 4-3-3 player, but at the very least would simply bombard down his flank and efficiently send in crosses nonstop.
I dont want Valencia as main options to get for us, chimed in on because he is so NOT "black" Pepe as mentionned, and I find his direct style more productive then Pedro's, atleast for a team who is limited, not already filled with class decisive players.
P.S Same archetype as Krasic, but what would differentiate them alot is footballing intelligence, Krasic has very little of it, while Valencia, who I have seen suffer in similar way Krasic has in "form", can adapt his play more then just keep repeating the same move/runs.
