Chelsea are set to bolster their midfield in the January transfer window by signing Inter Milan's highly rated midfielder Fredy Guarin.
The 27-year-old, who currently plays his trade at Italian giants Inter Milan is thought to be sold to the Stamford Bridge outfit, if Roman Abramovich is prepared to pay the £15 million asking fee.
The Columbian's agent, Marcelo Ferreyra, has said that Chelsea are finalising a deal with Inter Milan for the midfielder.
"Chelsea are trying to get the agreement with Inter." He said. "When that happens, Fredy will accept the move and the deal will be closed."
Chelsea are looking to strengthen their squad, with improvement clearly needed after their 2-1 League Cup defeat to Sunderland on Tuesday.
With the Blues constantly fielding Brazilian Ramires, as backup Marco Van Ginkel is out with a lengthy injury, it is thought that Fredy Guarin will help fill the void and produce that 'killer instinct' that Mourinho is demanding of his players.
His arrival at the Bridge could see the end of the road for long-term incumbent Michael Essien, who hasn't been the same player for a long time.
Guarin has 47 caps for his native Colombia, having made his international debut in 2006. He has had spells at Boca Juniors, Saint-Etienne, Porto and Inter Milan.
The Columbian has also been on Manchester United's radar in the past few weeks, though Mourinho seems confident he can attain his services, although failing to do so last campaign during his time at Real Madrid.
