The Italian, who has previously managed Juventus and Bari, feels that a club of Chelsea's stature must play in the Champions League.
"In the coming days, we can buy one, two, three players", he said.
Twelve months ago, Chelsea struggled in their warm-up games before embarking upon a disastrous defence of their English title which led to manager Jose Mourinho being sacked before Christmas.
"We must think about the present", Conte said in the Harris Suite at Stamford Bridge.
Terry, 35, signed a new one-year contract at Stamford Bridge in May to end speculation that he was going to leave the London club after more than 700 appearances. Without the lure of immediate Champions League football, the Blues are a less attractive proposition which in turn weakens the club's hand at the negotiating table.
Antonio Conte hopes to re-ignite Chelsea's title challenge.
"We know that, this year, it won't be easy for us because if we think about the last season and 10th position..." A shortlist of transfer targets will have long since been drawn up and discussed with owner Roman Abramovich and his cabal of advisors - and yet beyond Belgium worldwide striker Michy Batshuayi, a surprise £33 million acquisition from Marseille, the Russian is yet to splash the cash.
The most important thing is to work and for me to give an identity to my team, bring my idea of football, my passion, my work, and transfer my passion to my players and fans.
"You must build the best dress for the team and respect their characteristics", he added. "We take all decisions together with the club and I am very happy John signed", Conte said.
"The situation is a bit different", Conte said. "I'm very happy because I found a right attitude in Cobham (Chelsea's Surrey training base)".
Saturday's meeting will be just the second fixture between the two clubs in history, the first was a friendly in 1964 in which Chelsea won 2-1.
"The pressure for me is not important because I was born with pressure".
Conte does have the likes of John Terry, Oscar, Diego Costa and Asmir Begovic available for selection, as well as plenty of academy talent. With just a handful of training sessions under their belts, the Blues begin an important pre-season on Saturday, with four games to follow this summer.
