Saturday's scenes in the 3-0 home defeat to Burnley sent shockwaves through football which have also been felt over in Italy.
Roberts wrote on Twitter: "At least you will be able to see the football".
Brooking believes the level of stewarding, which is provided externally by the London Stadium operators, was not "sufficient".
"I had to take binoculars as I was that far away".
This, however, is widely regarded as a bargain and there is a possibility West Ham will offer a greater contribution to gain a broader influence over matchday security.
"The club are obviously going to have to look at things with the local police and make sure that trained stewards and police are in place - you're nearly looking at it and saying, "this is out of control", Brooking said.
His players kept their concentration on the pitch to claim their biggest win of the season, and he added: "It's tough on West Ham when it happened, it's their club, it's not really about us, the key for us was to stay focused, we couldn't do anything about it, it's just the way it is". Children and stewards were fleeing, fans were fighting: West Ham revived old times'.
"We got on with the performance and I was pleased with that". The LLDC said it was looking to strengthen security and would welcome financial assistance from the club.
"If they can reassure the FA and Premier League then, hopefully, you would like the game to take place in front of a crowd". I'd even go back to those days when Luton and Millwall had that riot back in 1985.
It was a very ugly and toxic scene. It was a awful, frightening scene and in the end, quite rightly, the West Ham staff coaxed people back into the boardroom before the final whistle because everybody was absolutely devastated by what might have happened.
The atmosphere at the London Stadium reached boiling point as protests on and off the field were made.
West Ham - who were set to jet off to Florida on Sunday for a five-day, warm weather training break - were not immediately available to comment on the crisis, but Brooking issued a plea to fans to shelve their concerns for the remainder of the campaign.
