The Italian delivered the FA Cup and Champions League to Stamford Bridge after taking over from Andre Villas-Boas in March and was rewarded with position full time by owner Roman Abramovich.
After losing Didier Drogba, Soloman Kalou and Jose Boswinga on free transfers it was thought Di Matteo would completely overhaul his squad and add to the signings of Eden Hazard and Marko Marin.
Porto striker Hulk is reportedly close to sealing his transfer to the West London club and could be joined by Brazilian teammate Maicon with the right back rumoured to be the subject of a £6 million bid.
A host of other names from around Europe and the Premier League have been linked with a move to the European champions but Di Matteo maintains he won’t be making wholesale changes.
He said: “I don’t think it will be an overnight thing. I wouldn’t expect radical changes.
“I would like us to be a good team that can compete and always in the frame for the targets this club has.
“I don’t think there’ll be a big overhaul of how we approach the games, new players will be integrated into the team and we will try and get the best out of them.”
The 42-year-old is still keen to bolster his forward line with Serie A duo Stevan Jovetic and Edindson Cavani in his sights whilst midfielders Cheick Tiote and Marouane Fellaini are still supposedly on his summer shopping list.
Wigan winger Victor Moses remains a target but Di Matteo isn’t prepared to fork out £12m and could turn his attentions to Theo Walcott who’s future at Arsenal is unclear as he enters the final year of his contract.
