IK Sirius midfielder Joseph Colley has recalled his time with Chelsea's academy.
Colley has returned to Sweden after four years with Chievo Verona.
On Chelsea, Colley told Fotboll Transfers: "It was cool. Coming from little Sweden and playing with players you see on TV in ordinary cases, it was difficult to understand that it was real. It is clear that you had to pinch your arm.
"Then you had to wash away those thoughts as soon as possible. They were training buddies and colleagues - not idols."
Asked about which senior players took most interest in the club's academy youngsters, the Swede added: "I would say David Luiz when he was there. He is a real joy spreader who clicked well with the young people. He was talked to a lot. And (Antonio) Rüdiger too. The two I would probably say."
