Chelsea goalkeeper Kepa Arrizabalaga believes Andreas Christensen will succeed with Barcelona.
The Dane will join Barca in a Bosman deal.
Kepa told Marca: "He seems like a very good player to me: fast, with a very good use of the ball, with a very good foot, who goes well up the pitch, who has a lot of experience for his age, more than 50 games for Denmark, and who has played football at a very high level.
"He wanted to change, look for something new and I think [Barça] is going to take a central defender for many years."
