Chelsea have no plans to make a desperate dive into the January transfer market, after Brazilian midfielder Ramires was stretchered off with a nasty looking knee injury in the weekend win over QPR.
The South American star has suspected damage to a medial ligament, which will rule him out of action for at least a month during a pivotal time of the season.
"It is a big blow because Rami is one of the most used players in the team and is a player with major production and major performance this season," he is quoted by the Fulham Chronicle.
"I would like to give you better information as we will reassess via the MRI and our doctor, as medial knee injuries can vary depending on the extent."
In the aftermath of the Loftus Road fixture, Villas-Boas was asked directly whether he would be looking to bring in short-term cover for Ramires.
"I don't think so," was his response. "As you saw today, we used Flo [Malouda] in midfield, have Lamps [Frank Lampard] to return, and [John] Obi Mikel to return.
"We have enough numbers to cope with it. If we add Flo to the midfield then even without Rami we have six midfield options and I think that is enough."
