Matheus Cunha went from ecstasy to despair as he followed his first Atletico Madrid goal by conceding a late penalty that Levante scored to salvage a dramatic 2-2 draw.
In his seventh outing since signing from Hertha Berlin in a reported €30million deal in August, Cunha appeared to have netted the winner with 14 minutes remaining at Estadio Ciutat de Valencia.
However, as Diego Simeone watched from the stands after being shown a second yellow card for dissent, Cunha was deemed to have handled the ball in the box when referee Pablo Gonzalez Fuertes reviewed footage on the pitchside monitor.
Enis Bardhi, who cancelled out Antoine Griezmann's opener in the first half, drilled in a second penalty of the game in the 90th minute to deny the reigning LaLiga champions the full three points.
Griezmann had put Atleti ahead inside 12 minutes with his first LaLiga goal since returning to the club from Barcelona, following up his cross and nodding home Felipe's header back into the middle.
Levante responded well to going behind and drew level in the 37th minute when Bardhi slammed home a penalty after Luis Suarez miscontrolled the ball in the box and fouled Ruben Vezo.
Atleti finally regained their lead when substitute Rodrigo de Paul drove forward and released Cunha – who only replaced Griezmann four minutes prior – to slot beneath Aitor Fernandez.
Simeone remained heated and was shown a second yellow card for remonstrating at the fourth official, with Atleti unable to hold on for the victory.
A harsh handball decision against Cunha resulted in a penalty that Bardhi confidently dispatched low into the left corner to send the home fans into raptures, though Rober Pier received a second yellow card after the final whistle for complaining to the referee.
