New Atletico signing Fernando Torres is hoping to make his debut for the club against cross town rivals Real Madrid when the clubs meet in the Copa Del Rey quarter-finals.
El Nino joined Los Rojiblancos as an 11-year-old, and went on to captain the team before leaving for Liverpool in 2007, but arrived back in Madrid on loan on Tuesday to a hero's welcome.
The Chelsea flop is back club where he scored 91 goals in 244 appearances on loan from AC Milan, and expressed his delight at his return to the Vicente Calderon.
"I'm excited, happy to have returned and looking forward to starting work. I've never needed to say anything to Atlético staff and fans, because they've said everything already, and as always I'm grateful to them", he told reporters in his first press conference.
"I'm looking forward to starting training and hope that I can already officially be an Atlético player on the 5th January".
