John Terry hung up on Kalidou Koulibaly because he thought it was a prank call.
Koulibaly rang the Chelsea legend to ask for permission to take his No.26 shirt after completing his £34million move to Stamford Bridge. But former Chelsea captain Terry did not believe it was really Koulibaly on the other end of the phone and insisted on checking it was not a wind-up.
Senegal defender Koulibaly, 31, who has signed a four year deal, wanted the No.26 because he wore the shirt at Napoli and revealed he also spoke to ex-Chelsea and Napoli star Gianfranco Zola for advice before moving to Chelsea.
