Mile Svilar made a horrendous error on his Champions League debut against Manchester United aged just 18. Romelu Lukaku consoled the young goalkeeper and they'd later become teammates at AS Roma. Svilar struggled afterwards at Benfica but is now developing into a top 'keeper under Daniele De Rossi in Italy.

There are few roles in football filled with the pressure that being a goalkeeper brings. It's a thankless job and one that can go either right or horribly wrong. Unfortunately for Mile Svilar, it went terribly wrong when he faced Manchester United in the Champions League during the 2017-18 campaign.

At just 18 years old, he became the youngest goalkeeper to ever play in the competition. For the most part, his performance against the Red Devils wasn't too bad. He made some neat saves and dealt with United's attacking play fairly comfortably; however, he looked shaky aerially, particularly when dealing with crosses into the area.

Despite a fairly solid showing overall, the inexperienced shot stopper's hard work was completely undone after he made an absolute howler to concede the only goal of the game. After United won a free-kick towards the left-hand touchline, Marcus Rashford whipped a fierce ball into the area and Svilar caught it fairly routinely. Sounds fine, doesn't it? Well, unfortunately, the goalkeeper was moving backwards as he caught the ball and the momentum saw him carry it into his own goal.

It was a disastrous way to end what had been an impressive showing ag.
