A consultation about excessive grappling in the penalty area and how to deal with it will take place at the end of the season, referees' chief Howard Webb says.
Webb confirmed the move after explaining why disallowing West Ham's last-ditch equaliser against Arsenal on Sunday was the correct decision.
The decision was controversial, giving Arsenal a 1-0 win and impacting not only the fate of the two clubs, but also Manchester City and Tottenham Hotspur at either end of the Premier League table.
Webb, speaking on Match Officials Mic'd Up, said the foul on Raya had to be penalised.
"Is it a foul on the goalkeeper? Categorically yes," Webb said.
"We've said all season, including in pre-season briefings with the players, that if a goalkeeper is impeded by an opponent grabbing or holding their arms and therefore they can't do their job, they'll be penalised.
"We're not just talking about contact with goalkeepers, we're talking about a specific type of contact when the goalkeeper's arms or hands are being interfered with, stopping them doing their job.
"Raya can't do what he would normally do in that situation, simply catch the ball or punch the ball, and they intervene, and they come to the right decision.
"When you look at that in the round, that's clearly the clear and obvious offence that needs penalising."

Grappling, holding and pushing has become a theme in the Premier League this season.
Webb said that, at the end of the season, discussions will be held about how to police it.
"We consult all the time with the clubs, with the fan groups, with a range of other stakeholders about the type of game that they want to see and how they want us to officiate it," Webb added.
"This season's been a little bit more unique than previous ones about the number of contacts in the penalty area, and it does create a challenge for the officials.
"We'll certainly continue consulting with all of the people I mentioned earlier about the type of game they want to see, because we have seen more involvement from set-piece coaches bringing players together in these areas, looking for those marginal gains.
"But we need to be vigilant. We need to identify those clear actions that are impactful.
"We've penalised more holding penalties than we did last year, but we've missed some as well."

AVAR: You've got that straight behind him as well, look.
RO: I'll go back to the original angle.
RO: Do you want to see it at full speed?
RO: No problem, just going to look now.
AVAR: Can you do a split screen on both of them as well?
RO: OK, goalline?
AVAR: I don't like Trossard not facing the ball and you've got…
AVAR: I agree, it's impactful, it's just everything else that's going on as well.
AVAR: What are we saying about Declan Rice behind?
AVAR: What's your initial opinion as you watched it?
VAR: Chris (Chris Kavanagh - REF), I'm going to recommend an on-field review for a possible foul on the goalkeeper but there are some other incidents to look at while you're at the monitor as well.
REF: OK.
VAR: So, I'm going to show you a possible foul on the goalkeeper.
RO: This angle?
REF: OK.
VAR: The left arm of Pablo comes across Raya and holds on to the left arm of Raya as he goes to win the ball.
REF: Yeah.
VAR: I'm showing you that now.
REF: I can see the clear holding on him across.
VAR: Yeah, but then I'm just going to show you some, obviously, other angles on that incident, of players.
REF: OK.
AVAR: You've got Declan Rice and you've got Trossard.
REF: I don't know what you're trying to show me, give me a clue.
VAR: Trossard on Pablo. Just if you look at Trossard on Pablo. Give me a better angle on that.
VAR: I'll get you a better angle.
REF: I don't think there's much in that at all, I'm happy with that.
VAR: Yeah, OK.
REF: That's nothing.
VAR: And then if you just want to consider the actions of Declan Rice on Mavropanos at the back.
VAR: But the foul happens on the goalkeeper before.
REF: Before it, so… After review, West Ham number…
VAR: 19.
REF: 19. Foul.
REF: Just confirm his number again for me.
VAR: 19.
VAR: Yeah, confirmed.
REF: Mic open.
REF: After review, West Ham number 19 commits a foul on the goalkeeper. Final decision is direct free-kick.
