Atletico Madrid manager, Diego Simeone has named defender Reinildo as responsible for allowing Manchester United to equalize late on in the first leg of their Champions League round of 16 tie.
The LaLiga side took the lead after Joao Felix headed past David de Gea in the seventh minute.
United levelled the game with 10 minutes left after Bruno Fernandes found enough space to play in Anthony Elanga.
Elanga calmly slotted the ball beyond Jan Oblak who himself was guilty of some questionable positioning.
But when asked by Marca to analyse the goal his team conceded, Simeone said: “Good play when the ball came out, Bruno makes a pass change and enables the run for a quick transition and they took advantage of the only mismatch we had.
“Reinildo could have solved it better, but we knew that in some transition it could happen.”
