Cesc Fabregas can see Chelsea teammate Thibaut Courtois moving to Real Madrid.
Courtois has been linked with a move to Real Madrid at the end of the season.
"It wouldn't surprise me at all because Courtois is the best goalkeeper in the world," Fabregas told Cadena Cope.
"It's normal that the best teams in the world want the best goalkeeper in the world.
"Chelsea is a top club and, for the future of this team, Thibaut is a very, very important player.
"That is more so considering Chelsea's future aspirations in terms of competing in the Champions League next season and winning the Premier League title.
"You need the best players to compete for the top trophies and Thibaut is one of them."
