It is better, of course, to start online after a career, when you have already pumped up. Moreover, it is extremely unbalanced here. Everyone pumps up forehand, backhand, strength, speed and reflexes, ignoring all other indicators. Therefore, if you want to keep up with all these reactive balls, you need to redistribute the pumping in the same way.
Here is a sample build.

You can pump up more reflexes to get into perfect time or stamina more easily, but +/- everyone pumps up like that.
And if both you and your opponent play well, the match will drag on for half an hour. Therefore, in order not to waste time and nerves, there is one trick here. When selecting an opponent, if you see that he is strong, with maximum pumping, then close the game before the match starts. The next time you enter the game, you will remain in the semi-finals/finals, the tournament will not start from the beginning, but will be in the same place as before the game was closed. Just make sure that the opponent is 10 levels lower, so that you can definitely win and not take risks. If you lose a match or drop during it, you will start the tournament from the beginning. Although I won the first tournament without playing a single match in full. Opponents simply dropped after the first games, by the way, the victory is counted for this.
