Chelsea have completed the signing of Brommapojkarna youngster Joseph Colley, according to the Swedish club's U19 boss Dali Savic.

According to the Mirror, the Blues will unveil the young defender as a Chelsea player once the transfer window opens on 1 July after Colley waved goodbye to his teammates last week in anticipation of completing his dream move to Stamford Bridge.

Colley is said to be a versatile player, who can operate as a right-back, centre-back or even as a deep lying central midfielder, making him quite a catch for the west London club.

Savic, who joined the club five months ago as the manager of the U19's, believes that the young defender is the best player born in Sweden since 1999. He also compared the defenders skills to that of Paul Pogba, who is a summer target for top clubs across Europe.

"Joseph is in my opinion best best player in Sweden born since 1999 [sic]. He is a leader on the pitch and in the locker room and has good technical and tactical skills already despite his young age," Savic said, as quoted by the Mirror.

"He is strong and has excellent timing with his headers. Chelsea are signing a top young player. I think JC is special and has a unique style of playing but if I have to pick one player [to compare him with] I would say Paul Pogba," the Bromma reserve team boss added.

"His athleticism and quick technique with ball is similar to Pogba. JC can play as midfielder but probably is he going to be excellent as a full-back at senior level," he explained.

Savic has revealed that the deal to move to Chelsea was agreed before he arrived, and feels that the newly crowned Premier League champions have bought a player of immense quality. The Blues have beaten off competition from domestic rivals Manchester United, who the report claims were also monitoring the 16-year-old defender with a view to a summer move.

"I saw his quality from the first training session we had and I knew that he was going to Chelsea. My mission was to keep him on his toes and make him work hard."

"I don't know what plan Chelsea has for him, but I hope and think he is good enough for Chelsea from day one. We have a good relation with Chelsea and the communication between the clubs has been excellent. JC was going over to London on a regular basis to train with them," Savic concluded.
