Chelsea manager Roberto Di Matteo has revealed he is keen on bringing in further new signings this summer as the likes of Luka Modric, Edinson Cavani and Hulk continue to be linked with moves to Stamford Bridge.
But the Italian has refused to name any potential transfer targets for fear of raising their price tags.
Porto striker Hulk has been on Chelsea's radar for some time, as has Napoli forward Cavani, although their respective clubs are refusing to negotiate on their valuations.
Hulk has a huge €100million buy-out clause in his contract with Porto and it is thought he will not be sold for less than €40m, while Napoli president Aurelio De Laurentiis last month insisted Cavani would only be allowed to leave the club this summer should his €70m valuation be met.
Chelsea failed with a £40million bid for Tottenham playmaker Modric twelve months ago but remain keen on luring the Croatia international across London this summer.
Di Matteo has already seen the Blues spend £40m this summer on Eden Hazard and Marko Marin from Lille and Werder Bremen respectively, and has been full of praise for his new recruits.
However, the former midfielder is giving nothing away on any potential future new additions to his squad.
"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," Di Matteo was quoted as saying by Sky Sports.
"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."
However, he added: "I am not going to discuss our targets. Every time you say something the price goes up."
