Playing a player of a lower level can be difficult. The ball comes in without pace, usually from a high trajectory. Work your feet harder to get into position. It's normal to match the level of your opponent in a match, so try to play your game, and when your level drops against a worse player, and you lose your confidence, don't push the ball. Keep hitting through your shots and put topspin on the ball. Ensure your footwork stays strong and get to the balls early so you can focus on effectively getting your body weight through the shot.
