"It was armageddon it was very strange."
He continued: "Me and my boy yeah we locked down, it was insane, what a year it has been for everyone in so many ways.

"I don’t get it, am I doing anything about it right now? no, I’d like to do something about it.
"I don’t understand how so many people can be on the street.

Sykes also asked Farrell if he was going home to Ireland soon.
Farrell perked up and said: "I miss it, I’m going back soon."
