The Premier League leaders confirmed the Colombia international’s arrival on a four-and-a-half year deal shortly after Andre Schurrle rubberstamped his move to Wolfsburg.
And the winger is happy to have arrived at Stamford Bridge, with the belief Jose Mourinho has shown in him playing a big impact in his decision to move.
He told the club’s official website: “I am very happy and thankful for this opportunity I’ve been given.
“This is a great club and honestly it is like a dream to join the Chelsea family and to know that the manager believes in me. I’m happy.”
The 26-year-old could make his debut for the Blues when they travel to Aston Villa on Saturday.
