In this Barcelona, it is necessary to be constant and to cling to one's spot because, otherwise, the place could eventually go to someone else. This is Dembele's case, who started the reason irregularly and is now paying the price.
The French winger has alternated good moments in the field with disrespect to the referee that have taken their toll. Mateu Lahoz reflected in the record that the player had repeated he was "very bad", so Competition sanctioned him with two games.
In this time, Antoine Griezmann has recovered from the bad performances suffered since he faced Betis and has earned the respect of Leo Messi and Luis Suarez. The Frenchman's performance against Eibar should be enough to earn him a spot in the line-up for the Champions League clash.
The Atletico player scored one goal and participated in the other two, sparking Ernesto Valverde's attention and therefore complicating things for Dembele, who has been sanctioned and could have potentially lost his spot for it.
At the moment it seems that Griezmann wins in full in the battle with the Frenchman, but the truth is that Valverde has a role because leaving one of them on the bench would not be the best option, which is to have all four tenors in good shape.
