My bad, here from 18/19, http://www.barcaforum.com/showthread.php/53-3-Gerard-Piqué/page849, absolute peak.
And this is about his non-football activities... probably the best you could find.
Most of the season he was prasied for his leadership and good play, and yes mats, Alba and Messi were better, he was still top5 at least. It doesn't make sense to single him out when he actually was pretty good. It also doesn't make sense to question that the players backed Valverde, when this was quiet obvious. Also, as said, board pushed Valverde to extend his contract while he preferred to wait Till end of the season. You clearly have an agenda to frame Valverde in a bad way.
