The former Manchester United striker scored the game-winning goal for the Gunners, giving Arsenal their second win against the Red Devils in 16 matches.

After a few months, Danny Welbeck earned a little payback against Louis Van Gaal. Arsenal's Number 23 scored the game's deciding goal against his former side, lifting the Gunners over Man United to reach the FA Cup semifinals. This victory represents the second time Arsenal has beaten United in their last sixteen games, while it's the first win for Arsene Wenger at Old Trafford since 2006.

Things turned out wonderfully for the Gunners, since they dominated the first half up to the goal scored by Nacho Monreal. The Spanish midfielder netted the ball after 26 minutes, and everything seemed to be working just fine for Wenger's men. But three minutes later, Wayne Rooney equalized after a fine cross by Angel Di Maria.

After the break, United dominated most of the action, but it was Arsenal who re-took the lead thanks to Danny Welbeck, who managed to score the decisive goal after a bad pass by Antonio Valencia. Things got more complicated for Van Gaal's men after Angel Di Maria was sent off. United enjoyed a few chances to equalize, but Szczesny's performance was crucial when his team needed him the most.

Fans praised Lord Welbeck's goal against his former team, while some others did not waste any time trolling Manchester United's season. Scroll down to read some of the best comments below!
