Dynamo Moscow’s Portugal international midfielder Maniche, who played under Jose Mourinho at Benfica and Porto, is close to signing for Chelsea.
The 28-year-old could join on loan until the end of the season, when Chelsea will have a £5m option to buy.
Dynamo sports director Boris Ignatiev said: “Talks with Chelsea are continuing but we’re in the last parts of negotiations.”
Mourinho would see Maniche as ideal cover for Michael Essien, who is set to miss at least three games while on duty for Ghana in the African Nations Cup.
Reports have also linked Mourinho with a move for Porto’s Argentinian midfielder Lucho Gonzalez.
