RB Leipzig goalkeeper Peter Gulasci will be having a sleepless night after his horrendous mistake during his side's 4-1 thrashing at the hands of Shakhtar Donetsk on Tuesday.
Marian Shved scored twice in a dream debut for Donetsk as the Ukrainians crushed their hosts in their Champions League Group F opener.
Shved was handed the first goal when Gulacsi tried to be clever with the ball in the middle of the Leipzig half.

After faking to pass a couple of times, he proceeded to miskick the ball, allowing Shved to steal in and roll it into the empty net.
The moment quickly did the rounds on social media with fans labeling it one of the worst goalkeeping errors in the competition's history.
Gulasci looked gutted and his night only got worse as he would let in a further three goals in what was a disastrous start to their European campaign.
