Real Madrid are pushing to sign Porto defender Eder Militao this month.
Knowing there is competition from Manchester United and Manchester City, Real want to reach a deal for the Brazilian as soon as possible.
Real are in talks with Eder's agents, though have been warned not to expect any quick decision.
Eder would prefer to bide his time and wait until the summer before choosing his next move. Porto, meanwhile, also have little interest in losing the defender this month.
Porto are demanding €50m as a starting price for the 20 year-old.
