Monaco striker Radamel Falcao has left the door open for a return to Atletico Madrid after taking on his former club in the Champions League on Wednesday.
Falcao came on as a substitute and missed an 83rd-minute penalty in a 2-0 defeat against Atletico that ensured Monaco will finish bottom of Group A.
The Colombia international scored 70 goals in 91 matches over two seasons with Atleti and was presented with a framed photograph prior to kick-off.
Falcao's contract at Monaco is due to expire at the end of next season and he hinted at a desire to return to the club where he won the Europa League in 2011-12 and the UEFA Super Cup and Copa del Rey the following season.
