Steve McClaren’s side prop up the Premier League after a winless start to the season, with Monday’s defeat to West Ham leaving them in desperate need of a win against the newly-promoted Hornets.
Janmaat: “It was a really disappointing night, but we have to forget it as quickly as we can now.
“We know we have to put a lot of things right. It’s a big game (against Watford) now.
“It’s important that we get that first win under the belt and Saturday is the next opportunity to do that. We have to win otherwise the pressure will only continue to increase.
“We need to get the balance right. There were times when we were trying to get men forward, but that left us open at the back and that cannot happen. We didn’t create that many chances, and that definitely has to improve.
“I try to get forward when I can, but collectively we have to offer a much bigger goalscoring threat.
“I try to join in, but I am a defender and that has to be my main job.
“It is not just about the attackers when it comes to scoring goals, but as a team, we have to find a way of posing more of a threat. We have to score more.”
