Suarez is a great dribbler with an amazing shot. Maybe he just doesn't suit the way you play? For me he's in the right place at the right time so generally don't have to use his pace. I use Bale and Nedved on Hunter so he has the pace on the wings. But seriously anything Suarez hits goes in. Best finisher in the game for me.
When the momentum shifts i try and slow play right down and keep posession out wide. Often shileding the ball and recycling the ball back from defense to midfield. I don't do any risky passess and try and hold out until half time. When your 2-0 up and the opponent can't get the ball they often get frustrated and fly in on tackles leaving space wide open.
