Alonso: We haven't had enough speed all weekend.

      Aston Martin racers completed the protocol of Sunday's race in Miami…

      Fernando Alonso (15th): "It was a tough race. We didn't have enough speed all weekend, and we knew it was going to be a difficult race for us. We faced the same problems as before and were unable to take advantage of the chaos that was in front of us. We need to improve, and I hope that we will take a step forward in Imola."

       Lance Stroll (16th) "A difficult race in difficult conditions. We just don't have enough pace – we've been outperforming all season, and today was no exception. Once again, we were convinced that we were not competitive and had to improve the car in all areas."
