Director of Rugby Ruddock remains upbeat about the coming months with new signings Sam Tuitupou and Rico Gear set to feature in the next round of top-flight games.
However, he admits the entire side need to start clicking into gear to pull away from early season trouble.
"We have got players to come in like Sam Tuitupou, Greg Rawlinson - who made his debut in the second half with Sale and Rico Gear - they can be like Luke McAlister was for Sharks and make a big impact," he said.
"But we can't just rely on them to come in and deliver, we need to be better as a team and push on together if we are to start getting results."
Ruddock was full of praise for the way star-studded Sharks had clinically claimed the points despite Worcester enjoying large spells of possession and territory.
And he highlighted the spell when Sale were down to 13 men in the second half as the crucial period.
"We were disappointed to give the last try away and it really shifted the balance much wider than it should have been," he said.
"The crucial period was Sale having two players in the bin. We let that slip when we should have been on the front foot. Penalties then suddenly had us on the back foot and the chance slipped away
"I'm disappointed with the early scores we conceded, we started slow and didn't have the edge we wanted. We fought hard to get back into the game but when you have given up points early it is hard, we lost our way in the opening 15 minutes. I expected more and we need to deliver. But credit to Sale they took the chances and fronted up.
"Their kicking game put us on the back foot in the first half, we couldn't pressure them in the tight and they made it very hard for us. They are an excellent team we have got to be disappointed."
