While many football fans were watching a rather dull Manchester derby in the League Cup on Wednesday night, there was an equally intriguing clash in Italy.
Out of form giants Inter Milan, hosted Torino, who Premier League fans have become a lot more aware since Joe Hart joined them on loan from Manchester City.
The England goalkeeper has enjoyed a relatively quiet start to life in Serie A but he made his biggest mistake to date by gifting Frank de Boer's men the opening goal of the game.
With just over half an hour on the clock, Inter's Antonio Candreva had seemingly overhit a through-ball in the Torino box, initially aiming for Mauro Icardi.
Hart actually reacted very quickly and sprinted off his line to collect the ball.
And although Icardi continued to chase it down, it looked like a lost cause.
However, the Inter captain was rewarded for his persistence as rather than just catch the oncoming ball, Hart parried it straight into Icardi's path.
You can watch the pretty horrendous gaffe in the video below, as the ball ricochets off Icardi's shin before bouncing into the back of the net.
Arguably the best part of the clip is actually the Torino manager, Sinisa Mihajlovic's reaction.
The 47-year-old shook his head in utter dismay that his keeper could present such an opportunity to the opposition - particularly when it is a team so low on confidence at the moment.
Icardi has had his own well-documented problems to deal with of late and ending his four-match goal drought could go some way to boosting his morale too.
Torino might have even been considered favourites before the first whistle but Hart's mistake has given them an uphill task for the second half.
Don't worry Joe, at least Pep Guardiola hasn't seen it - yet.
Here's how Twitter reacted to the howler:
