Now, I have got the chance to play quite a few games with this man, as I packed him untradeable right after the second future stars batch came in packs. I have played my full weekend league with this man, and he has not let me down. FFS Valverde is the definition of a solid box to box midfielder. I play him on RCM in a 4-1-2-1-2 narrow with an engine slapped on him. His passing en dribbling is absolutely perfect for me. He can bang in a long shot when he has to and is very decent defensively.
His stamina, coming in at only 84, is letting him down a little. In my opinion, it is not representative of his real-life performance at all as well. This lead him to be subbed off for extra-time games, which is just a shame because when you get a 1M coins player you would love to play him every game for the full time. Also, his 3-star combo is not the best, and if you are a skiller it will be annoying for you, but as I like to play through the defence with quick passing I have not noticed this too much, and who knows he might get a skill/wf upgrade in the winter upgrades.
