Atletico Madrid head coach Diego Simeone felt his side paid the price for "not being forceful" enough as a 92nd-minute Radamel Falcao penalty earned Rayo Vallecano a late 1-1 draw on Tuesday.
Alvaro Morata's first-half strike looked to be enough to give Atletico their fourth straight LaLiga win, despite missing a number of chances to add a second goal.
They were left to rue not taking those opportunities, as the referee awarded a penalty after Jose Gimenez handled in the box from Randy Nteka's header, before Falcao fired home the penalty to deny his former side the win.
Simeone was frustrated over his side's inability to kill the game off, telling reporters: "We had good goal situations to score the second and close out the match.
"The second was not scored and we remain in a situation in which they can equalise.

"In the second half we had a lot of counter-attacks to finish the game, we didn't convert the much-needed second goal and we lost two important points."
The two dropped points Simeone referenced would have put Atletico just three points behind leaders Real Madrid, and the 52-year-old feels his players must be more ruthless in future.
When asked what his team did wrong against Rayo, Simeone replied: "Not being forceful.
"If you come up against the goalkeeper several times, it has to be a goal.
"You have to improve the forcefulness and train it and when that situation appears, there is the mettle to finish."
