He left with tears in his eyes and promised it would be a "see you later". Now, the retired footballer wanted to visit his ex-teammates.
Fernando Torres appeared at the training by surprise. No one expected it.
The number 9 is in Madrid to visit his favourite team. He spoke with the dressing room about their start to the season.
According to 'AS', he entered the dressing room with the rest of the players. He encouraged them and recharged their batteries for the match against Real Madrid at the weekend.
El 'Niño' knows that the match will be tough, but he has all the confidence in their world in the players. He hopes his visit helps and Atletico get the three points.
