Diamond, 47, says some internationals could join Sale at the AJ Bell Stadium in time for next season.
"We're in talks with four or five international players to join us," he told BBC Radio Manchester.
"We're well on the way to bringing some real experienced quality players to the club next year."
Diamond said there is no urgency to bring in players and that he was happy with the way the club plans to bring in recruitments.
"I don't need to rush into signing players. We've got a good protocol with how we find our players and it's not let us down yet in five years," he said.
"There's offers gone and there's offers been accepted, we've just got to tie the details up.
"There's one or two people who have decided to come to Sale for less money than they're being offered.
"They've got mates who are here and they've asked the question. How do they run it? What's it like?
"One or two of these are leaving big clubs to come here which will be a statement when we announce them."

Duffy, 26, raced into a 3-0 lead and beat the world number nine easily.
A furious Ding criticised the playing conditions at the York Barbican.
Sheffield's Duffy, who is seeded 121 for the event, said: "I was confident going into the match because I have been working harder than I ever have before, but it's crazy. I am buzzing."
Ding's news conference lasted less than a minute and was littered with swear words.
The Chinese star complained about the table set-up and conditions and will be lucky to escape a fine from World Snooker for his rant.
Three-time UK Championship winner John Higgins had no problems coming through his first-round match.
The 40-year-old Scot, who has already won two ranking events this season, continued his impressive form with a routine 6-1 victory over Leo Fernandez.
Higgins is joined in the second round by three-time runner-up Ken Doherty, Mark Davis, Antony McGill and Sydney Wilson, who came from 4-2 and 5-4 down to stun Welshman Michael White in a thrilling final-frame decider.
Doherty, 46, thumped fellow veteran Tony Drago 6-0, world number 20 Davis beat Rhys Clark 6-1, while Scotland's McGill scored three centuries in a 6-3 victory over James Cahill.

Blackwell retired from boxing after he suffered bleeding on his skull and was put in an induced coma in a loss to Eubank in March.
Eubank Jr will be defending his British middleweight title for the first time.
"I'm not going to let a situation like what happened in my last fight affect my future performances," he said.
The fight against unbeaten Doran, 28,  is on the undercard of Anthony Joshua's IBF heavyweight title defence against Dominic Breazeale at London's O2 Arena.
Blackwell woke from his coma a week after the fight, which was stopped in the 10th round, without requiring an operation.
Eubank Sr, who was a two-time world champion in the 1990s, admitted he lost his killer instinct after the 1991 rematch with Michael Watson that left the latter with near-fatal brain injuries.
But Eubank Jr, 26, said that would not happen to him as he and his father are "two different men".
He added: "Something like that might affect someone's fighting style and mindset. For me, I've used it to fuel myself even more.
"I'm in there to win, defend myself and attack, and to further my career, so there is no mercy.
"It's the referee's job. It's not for me to have to say I should ease up."
Sale Sharks director of rugby Steve Diamond says the club will not rush into making signings and insists they will bring in "quality" talent.
