I don't buy that.
For example -- last season's match against Silva's Watford (Unsworth in charge). We're defending a one goal lead late in the match, Watford are probing for an equalizer. We have a solid defensive shape, Watford have possession in a harmless part of midfield. Gana makes a mad dash to go win the ball, Watford work the ball around him and pass through the space he vacated to win a penalty. Pressuring the ball isn't some virtuous pursuit in this situation. We were winning, we were well positioned, Watford were up to absolutely nothing. Ultimately, we were lucky that Cleverley took an awful penalty.
Gana's game is full of these little gambles to win possession back, regardless of whether or not we need to win it. It's why I hate it when we give him any sort of positional freedom. I think all of his best football is played when he stays in his own half and moves side to side to break up or slow down counterattacks.
Of course there are instances where Gueye is singularly at fault because of his over exuberance, as you rightly have pointed out here. But I don't think that is wrong that Gueye will fair better in a team that works, and presses, as a team better than we did this past season.
