This is commonly called a first contact, testing the waters or seeing what's cooking.
The player came close to being included in the current Spanish National Football Team participating in the Euro 2012 competition. The player has exploded onto the scene & is considered a serious promise in European Football. Atletico has Adrian in a low salary bracket & if this is not bettered, it could be an "excuse" for the player to look elsewhere for his future. FC Barcelona could pressure & put on the table 18M€ which would help enormous Atletico hold onto Falcao. But this is all speculation & Football transfer rumour talk at this moment.
Stay tuned for developments.
