Tottenham Hotspur are through to the fifth round of the FA Cup following a 3-2 win over Southampton on Wednesday night.
Jack Stephens' own goal put Spurs ahead after 12 minutes, but the visitors responded in style and were well worth their 2-1 lead after 72 minutes given to them by Shane Long and Danny Ings either side of the break.
But the host rallied and prevailed in the five-goal thriller thanks to goals from Lucas Moura and Son Heung-min.
And some rival supporters aren't happy with the outcome.
Not because Spurs are in the fifth round, but the manner in which the north London outfit went ahead for the second time on the night as Son was brought down by Angus Gunn in the penalty area.
The official immediately pointed to the spot and the South Korea made no mistake from 12 yards.
However, replays did show their was minimal contact from the Saints goalkeeper on Son, but Spurs fans and Jose Mourinho won't be too worried about that.
Although, that can't be said for Liverpol
Much of the reaction has centred around the soft penalty with some even accusing Son of going down far too easily.
Take a look at what's been said on Twitter...
Speaking after the game, Mourinho conceded his team were lucky to overcome the Saints.
"I have to honest and I think the best team lost, the best team on the pitch lost," he told BT Sport. "But the team with more heart, the team where the players went to their limits, the team that had so many difficulties even to build a team, a team that on the bench the options were not options to change the game.
"Even Dele, in so difficult conditions, so I think my team deserved to win. The best team lost but my team deserved to win.
