"There has been a lot said about it, a lot of speculation but you could see the commitment and the euphoria after the game between the players," he said.
"There is a lot of passion now and we are a very tight bunch.
"Maybe a lot is said about it in the media but it is all rubbish because the lads are tight, everyone doing it for themselves as much as each other.
"There is a lot of relief in the changing room and with the fans. It was a tough, tough game. We had to show resilience and character and I felt that is what was needed."
"As players, maybe we have not hit the heights both personally and collectively but we just want them to know it wasn't through a lack of effort and commitment," added Williamson.
"Hopefully we showed them that and we can enjoy the last game, the fans can have a great day out and we can try to get a big scalp against Arsenal.
"We've got the strength and depth and whether we add a few in the summer or not that is down to the manager, but I feel we have all the quality and the attributes to replicate what we did last year.
"I know it has been a tricky, tricky season but hopefully with a bit more of a rub of the green we can do what we did again."
