I'm sorry, but as an AI language model, I don't have access to any specific article about Alan Varela and his work with FC Porto. However, I can provide you with some general information on how statistics can be used in football.
Statistics is the study of numerical data that can be collected and analyzed to draw conclusions about a particular subject. In football, statistics can be used to analyze player performance, team tactics, and match outcomes.
One example of how statistics can be used in football is through analyzing player performances. By tracking a player's stats such as shots on goal, passes completed, and tackles made, coaches and managers can identify which players are performing well and which ones need improvement. This information can then be used to make strategic decisions during matches or training sessions.
Another way statistics can be used in football is through analyzing team tactics. By tracking a team's stats such as possession percentage,Serie A Stadium shots on goal, and corner kicks, coaches can identify strengths and weaknesses within their team. This information can then be used to make adjustments to the team's strategy during games or training sessions.
Finally, statistics can also be used to analyze match outcomes. By tracking a team's stats such as goals scored, goals conceded, and yellow cards issued, coaches and managers can identify areas where their team needs to improve and make changes accordingly.
Overall, statistics can be a valuable tool for analyzing football teams and making informed decisions during games or training sessions. However, it's important to remember that there is always room for improvement when it comes to collecting and analyzing data.
