London coach Danny Ward said he was disappointed with his side in their Challenge Cup defeat at Leigh.
The Broncos were knocked out of the Ladbrokes Challenge Cup after losing 40-0 to Leighin the fifth round at the Leigh Sports Village on Sunday.
London currently sit in fourth place in the Betfred Championship table, two points behind third-placed Toulouse Olympique but with a game in hand.
And despite Ward being happy with their league position, he admits they need to improve.
Speaking after the game, Ward told loverugbyleague.com: “Leigh were outstanding and they looked like a Super League side and they made us look like a Championship side.
“Leigh were great but we need to be a lot better than that and I’m disappointed with our overall performance.
“We were in it for about 15 minutes and then they seemed to go up a notch. We cracked first and came up with a poor error and then we started making bad reads in defence.
“Leigh went up a level and scored three back-to-back tries and we didn’t have an answer for it. There are lots to work on for us.
“We are still in a decent position and we are still happy with where we are at. We are still in the top four and we have still got a game in hand, so we are happy at the minute but there are lots of work to do.”
Toronto Wolfpack, Featherstone Rovers, Toulouse, Halifax, Leigh and London all share the same ambition of gaining promotion to the Betfred Super League this season.
And with competition for spots in the top four hotting up, Ward says the Championship has never been better.
He added: “Leigh, Toulouse and Toronto are all up there and then the likes of Featherstone and Halifax are doing great as well, so the league is really strong and competitive.
“You have got to be on your game every week which is great for us. We know that we are going to be tested every week.
“There is a little bit of a gap between Super League and Championship, but anything can happen once you get in the top four and turn up on the day.
“I do like the format of the Middle 8s, I think it throws up some close games. From my point of view, it is exciting, but I am always up for change as well.”
Kieran Dixon suffered a dead leg in their defeat at Leigh, while Api Pewhairangi took a knock to his hip. Dixon should be okay to play against Dewsbury Rams next week but Pewhairangi will be assessed further over the next few days.
