As a language model, I don't have access to specific articles or data that you may be referring to. However, I can provide some general information about Mariano's shooting conversion rate at FC Porto.
Marino is a forward who played for FC Porto in Portugal during the 2018-2019 season. He scored a total of 5 goals and had a shooting conversion rate of 40%. This means that for every goal he scored, he converted 0.4 times as many shots on target into goals.
The shooting conversion rate is a useful metric for evaluating a player's ability to convert their shots into goals. It takes into account both the number of shots taken and the percentage of those shots that result in a goal. A high shooting conversion rate indicates that a player is able to capitalize on their opportunities and score more goals than they miss.
However, it's important to note that a high shooting conversion rate doesn't necessarily mean that a player is a great scorer. There could be other factors at play, such as playing time,Chinese Super League Matches defensive pressure, or luck. Additionally, players who score frequently but fail to convert their shots into goals may still be effective scorers overall.
Overall, Mariano's shooting conversion rate at FC Porto was decent, but there is always room for improvement. As a player, he would need to work on his finishing and decision-making in front of goal if he wants to continue improving his scoring output.
