Recent reports have suggested that Spanish giants Real Madrid and Barcelona were lining up moves for the Brazilian international.
However, Ramires insists he knows nothing about the rumours and that he is only focused on doing his best for Chelsea.
"Many people are asking about the supposed interest from other clubs in my football but I don't know anything, apart from what was reported in press," Ramires told Lancenet.
"I am under contract with Chelsea and my attention resides solely in keeping on doing the good job done at the club."
Turning his attentions to Brazil, Ramires is determined to keep his place in Luiz Felipe Scolari's squad with next summer's World Cup finals in mind after featuring in the recent friendlies against Honduras and Chile.
"It's always better to win and thank God I returned home with another fulfilled goal," added Ramires.
"We are in the final stretch for the World Cup so whenever I had the chance to play I try to always do my best so I can assure my place in the squad for this competition, which is the most important one in Brazil's national team history.
"We played our last friendly of the year and now I am focusing again on Chelsea until the next national team call-ups."
