Jonathan Mills insists London Welsh will have a lot of work to do ahead of next week's trip to Gloucester after they fell to a 42-15 LV= Cup defeat to Exeter Chiefs at Oxford's Kassam Stadium yesterday.
Despite leading 9-8 at half-time and being within touching distance for much of the game, Welsh were limited to just 15 points from the boot of Gordon Ross.
A Mark Foster try in the second half opened the floodgates and Nic Sestaret and Jack Nowell both grabbed two tries to enable the Chiefs to ease away and secure a bonus-point victory.
With Exiles coach Lyn Jones only making six changes to the side which beat Bath last week, back-row forward Mills admitted he expected a lot better from his side.
"It wasn't the way we wanted to start our LV= Cup campaign at all but fair play to Exeter, they came here and they played and threw the kitchen sink at us and it was successful really," he said.
"I don't think we were good enough in a number of areas. In the first half it was close but those errors were still there and it's tough to get into a game when that's happening.
"We've just got to get our basics better. The amount of missed tackles and silly knock-ons was just unreal and against professional teams you can't afford to make those sort of errors so we will definitely need to improve."
Jones was not too disheartened, despite the defeat. "We were quite competitive for the first 40 minutes," he said. "I was quite pleased with certain aspects of our game. Our set piece and line-out was strong but give full credit to Exeter, they played flat out.
"We got it back to 18-15 but then the white flag came out for the last 20 minutes as we lost our shape."
