The forecast for the match between Roberto and Alex strongly favors the latter. Taking into account high technical execution and quick reactions, the arguments point to the advantage of the Australian in this encounter. It is expected that he will be more agile and quick in exchanging strikes, giving him a significant edge. Roberto, as per the text, significantly lags in these aspects, making it challenging for him to compete. A reliable strategy here would be to bet on Alex's quick victory through a low game count. All these factors point to high chances for Alex to have a successful start to the tournament and to win against the Spaniard.
