Athletico Paranaense manager Luiz Felipe Scolari has revealed that he believes Chelsea transfer target Vitor Roque will one day ‘be world-class.’

The 17 year old is able to play across the frontline and is also attracting interest from other European clubs.

Felipe said about the 17 year old: “He’s a jewel, spectacular, pure. Hard worker, but still developing at 17.

“He turned pro at 15. Some things to work on… imagine in 2 to 3 years. Mentally he’s spectacular. Good kid. He’ll be world-class.”

Meanwhile, Chelsea are looking to sell centre-back Kalidou Koulibaly next summer, according to Italian media outlet Tuttomercatoweb via Goal.

The Senegal international joined Chelsea from Napoli last summer but has so far failed to impress fans at Stamford Bridge.

The former Napoli center-back is considered an expendable asset at Chelsea and could be on the verge of returning to the Serie A next summer with Inter Milan interested in signing the centre-back.
