Sweep to Omoplata from De La.
Take a de la riva guard. Inside leg against their thigh, sit on their foot if possible, outside foot wraps around their leg. Outside hand holds their foot, other hand grabs their closer wrist. Push them away with your leg, and drag their wrist accross and infront of their body. If they try to move your foot off their thigh, circle and replace it. Drag their wrist infront of their body to your side. From here can sweep to Omma, with their thigh pushed far away. Can readjust the Omoplata to flatten their chest against the floor.
