Lenglet has cost his team points in three important Barca games this season. The French defender, who is not in good form, has had several bad performances and he conceded the penalty which gave Cadiz a draw at the Camp Nou.
On all three occasions, these mistakes cost Barca points. They would have almost certainly beaten Cadiz had it not been for the penalty.
Lenglet frequently takes risks in the box and it makes Barca even weaker at the back. Barca conceded four in the Champions League game with PSG and that was more proof of Barca’s leaky defence. Not even starting Pique could solve things.
