Monitors the transfer market for players from a specific country and clicks age 19 button on specific search page
Userscript requested by user waffle. It will alert you if a player from a specific country is put on the transfer market. It is mostly useful for countries with few players on the market.
You can change the country being monitored in the transfer market page (there will be a clickable flag below the usual filters).
It can take up to 6 hours for the alert to show up (the check interval can be adjusted in the code via CONFIG.CHECK_INTERVAL_HOURS).
