Chelsea are said to be ready to trigger the £25.3million release-clause in order to sign Benfica star Nicolas Gaitan in the summer, according to reports from the Metro.
The 27-year-old was also previously linked with a move to Manchester United after new signing Angel Di Maria urged manager Louis van Gaal to bring him to Old Trafford, but to no avail.
Gaitan can play on both sides of attacking midfielder as well as straight down the middle, and appeals to Jose Mourinho with the Blues still keen on bringing in additional reinforcements ahead of the new campaign.
The Argentina international is currently being monitored by scouts from Stamford Bridge, while a formal offer may be tabled once the upcoming transfer window re-opens at the end of the season.
He has been a consistent performer for his side, making 34 appearances while finding the net four times, and has already provided 16 assist so far over the course of the campaign.
