There is no chemistry between Dias and La Porte.
Not making excuse for Dias, but La Porte situational awareness under any sort of pressure is shocking. He is an accident waiting to happen. We get away with it most weeks because most teams don't have the ability to hurt us.
We had that Dias/Stones partnership where we went a dozen games without conceding even a Goal. La Porte returned from injury, Pep broke up the partnership and chemistry and we started conceding Goals again.
Really don't rate La Porte never have.
