GIANFRANCO Zola insists Watford will not be fazed by in-form Millwall when the two sides go head-to-head at Vicarage Road on Tuesday.
The Lions are currently on a seven-game unbeaten run and make the short trip up the M1 as the division's highest scorers away from home.
But Zola, who took charge of the Hornets in the summer, says he will focus on his own players ahead of the match.
"I am not concerned but I am respectful of Millwall," he said. "You can't underestimate them and we won't because the Championship is difficult every week.
"I know that they will come here and have a go. They are confident and they are in a good moment. But I am not looking at them. I'll be looking for answers from my players.
"It's a game for us to show how mature we are. It's certainly a game we can win if we play at our best."
Striker Darius Henderson, who scored 29 goals in three years at Watford, netted in Millwall's 4-1 win over Nottingham Forest on Saturday and Zola admits he will be one of several danger men.
"Henderson is certainly a threat, as is Chris Wood," he said. "We will have to look after them.
"Hopefully we will give Millwall a few problems to handle as well. Their team is strong and organised, so we'll have to be clever."
