LIAM Trotter felt scoring an early goal was the key to Millwall's 3-0 victory over Luton Town in the fifth round of the FA Cup on Saturday.
The Lions set up a quarter-final date with Blackburn Rovers next month after disposing of the non-league Hatters at a sold-out Kenilworth Road.
And Trotter believes Henry's 12th-minute opener was crucial in dampening the spirits of the home fans. He told NewsAtDen: "Luton had done well in the last two rounds so it was a tough game.
"But we set out with a good attitude and I think we matched them physically as well. That little bit of quality between the divisions showed in the end and we scored three good goals.
"In these ties, if you are the team from the higher league the first thing you want is an early goal. It takes the pressure off and it deflates the opposition.
"We got that early goal – it was a really good finish from James – and Luton had an uphill task from then on. From there we didn't look back.
"The back four put in a really good performance and we showed what we really needed to show, which was a good attitude, to match them. It was a good team effort.
"But this game is already forgotten for us. We're focused on playing Peterborough on Tuesday – the league is our bread and butter and we need to get our form right. We need to get a good result."
