Selhurst Park saw a long-awaited return celebration for Roberto Firmino on Saturday evening.

It seems as if this goal was more important to the Brazilian than any other in the past year.

His strike to seal the 4-2 win over Crystal Palace represented the second time he took his shirt off after a goal, the first coming after Arsenal.

'So what?' you ask. That might sound like an unimportant landmark.

But not when you consider he's contemplated it so many times before.

One Twitter user, @MrBoywunder, has unearthed a remarkable number of Firmino goals where he celebrates by starting to take off his shirt - before thinking better and saving himself a yellow card.

He's done it against Manchester City twice last season, as well as Manchester United in the Europa League.

He has also thought about it against Leicester City in the 4-1 win in September, not to mention on international duty for Brazil.

But against Palace, he went all the way - picking up a yellow card in the process.

The forward could have cost Liverpool a goal, however, as he had taken off his shirt before the goal went in.

By the laws of the game, could that have been a booking and an indirect free-kick to Palace, right on the goal line?

The law reads: "If play is stopped to caution the player, an indirect free kick shall be awarded to the opposing team from the position of the ball when play was stopped."

This is a grey area, according to one refereeing source, as goal celebrations which see a caution for taking shirts off are administered because of unsporting play.

Common sense should be applied in Firmino's case, as it could create a situation where opposition players take off shirts when a striker is through on goal to halt play (although advantage could also be played).

Now there's an image.

But because it is not a goal celebration, as the ball hasn't crossed the line, he could have seen the game stopped.

An extremely unlikely scenario, of course, but still too close for comfort for Firmino.

Still, nice tattoos, and a great celebration.
