Millwall's Under 18s go in search of a place in the Semi-Finals of the FA Youth Cup on Thursday evening - and Sean O'Brien "can't wait" to get going.
Larry McAvoy and Chris Perry's young Lions face a daunting trip to multiple-time winners Chelsea on Thursday evening (kick-off 7pm), but the midfield man told millwallfc.co.uk all focus is on upsetting The Blues at Stamford Bridge.
"Everyone is excited and we're focused," he said. "We've prepared well and had a good win against QPR in the League at the weekend. When it comes to the night, nerves may be flying, but once everyone is on the pitch we can play our game and hopefully get a result."
Millwall will be backed by 1,000 fans in West London, with O'Brien - who has scored in every round of the competition so far alongside Abdul Abdulmalik - piling all the pressure on to The Lions' opponents.
"It'll be a great night for everyone involved - I'm really excited. I can't wait to play. Everyone is looking at us as the underdogs, which may favour us as the pressure is all on Chelsea. Hopefully we can cause an upset."
