Watford manager Nigel Pearson told BT Sport:
"It is a really strange day. For the players who thrive on atmosphere and emotional attachment, it will be difficult to get used to.
"We want our fans back here when it is safe, our responsibility in the meantime is that when they come back here next it is for Premier League football."
"It was a great pass to Ben Chilwell for the goal and we have said to him that he has a great strike on him," said manager Brendan Rodgers.
"It was sweet and could have won the game but it wasn't to be. But in patches we were good and in the course of time will be better.
"We felt we had done enough to win it. Kasper made some good saves but Ben Foster had to make them too. We will take a point and move on."
