Chelsea coach Roberto Di Matteo admitted the Blues would bring a few more new faces, but refused to divulge any names.
Speaking at his first press conference for the upcoming season, Di Matteo also elaborated on Chelsea's new signings.
The European champions have already inked deals for Belgium international Eden Hazard from French Club Lille for £32 million ($50 million) and Marko Marin from Werder Bremen for a little over £7 million ($11 million).
"Hazard is a wonderful player, a fantastic player and has achieved a lot at such a young age, winning the Ligue 1 player of the year," the Italian manager said.
"Marin is another talented young player who can play in a variety of positions, which is helpful for the team.
"I'm pretty happy with the team but we will look at the market and if there are any opportunities to improve the team then we will pursue it."
Chelsea have been heavily linked with another exciting talent in Brazilian striker Hulk. However, news on the signing has gone down a bit over the past couple of weeks. Asked about the possibility of bringing in Hulk, Di Matteo said: "I am not going to discuss our targets. Every time you say something the price goes up."
Di Matteo also revealed that the futures of veterans Florent Malouda and Yossi Benayoun, who are expected to move on, have not been decided.
"They are part of the club and I expect everyone to be here at the start of pre-season. We will monitor it and see what happens."
The 42-year-old was given a two-year contract by Chelsea owner Roman Abramovich, after the Russian billionaire reportedly failed to convince Pep Guardiola to end his sabbatical early. However, Di Matteo said he does not feel any extra pressue.
"I don't feel any shadow above me or behind me," the Italian said. "There has been speculation about other managers since day one and I have always lived with it pretty well.
"Everyone can say what they want. I will just focus on my job and try to do the best I can. I'm pretty happy with my new contract and that's why I signed it. But I have been in this sport all my life and I understand how this business works. I clearly know that managers are judged by results.
"It's no different for me than anyone else. The pressure is always there.
"Chelsea are always looking to win things and last season was not easy even if the end of the campaign was a pretty fantastic time."
Di Matteo was accused of using negative tactics, despite leading Chelsea to the FA Cup and Champions League titles. The Italian, however, said there would be no major changes to his style of play.
"I wouldn't expect radical changes. 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.
"I don't see any reason to change. I am the way I am -- this is me. The way I operate is me and that's not going to change in the future.
"I have my way to communicate with the players and I will continue with that.
"My job is to make them feel confident and to put their talent for the service of the team and try to win games.
"We certainly have to make up ground (in the English Premier League) because we finished 25 points behind the leaders so that's going to be a big job."
