As an AI text-based model, I can provide you with a basic outline and implementation concept for a simple text-based FIFA game using JavaScript in a single HTML file. Please note that this implementation will be minimalistic and won't involve graphical elements or pictograms as specified. It will focus on the core functionality of a FIFA game. Keep in mind that this is a general concept, and you can modify and extend it further to suit your requirements for a complete game.
In the above implementation, the game starts as soon as the HTML file is loaded. It simulates 5 matches between two players (`player1` and `player2`). The winner is determined randomly using `Math.random()`, and the scores are updated accordingly. Finally, at the end of the 5 matches, the game displays the player with the highest score as the overall winner.
To play the game, simply open the HTML file in a web browser's developer console or view the console output to follow the match results and the winner.
