Alisson had a complete meltdown as his howler handed Lyon a penalty in the opening minutes of Liverpool's match at the Stade de Geneve in Switzerland.
The Brazilian, 26, returned to the starting XI after his heroics with Brazil in this summer's Copa America.
But the Liverpool shot-stopper's return started off the
worst way possible as he misread the ball that was whipped into the box from
Memphis Depay.

Alisson desperately tried to clear the ball after he dropped it and it bounced between his legs, only to bring Moussa Dembele down as he tried to poke the ball into the back of the net.
The former Roma shot-stopper received a yellow card and Lyon were awarded a penalty.

And ex-Manchester United player Depay, 25, stepped up and fired the ball straight into the left corner of the net, sending Alisson completely in the wrong direction.
Roberto Firmino pulled Jurgen Klopp's men back into the match in the 17th minute.
The Liverpool forward, 27, also returned after an extended break and rose
to the occasion when Xherdan Shaqiri's deflected cross fell into his path.
And Firmino spun quickly to leave two defenders around him
helpless as he buried a low and powerful shot into the far corner of the net.

And the Reds took a 2-1 lead into half-time after Danish defender Joachim Andersen bundled the ball into the back of his own net.
