Andreas Christensen has revealed how he turned to Chelsea legend John Terry in an attempt to banish costly errors from his game.
Christensen has broken into Antonio Conte's team this season with a series of mature performances.
The serene progress was halted by a hamstring injury and, upon his return, a clanger against Barcelona which gifted Lionel Messi an equaliser at Stamford Bridge, in the first-leg of a Champions League last-16 tie.
The 21-year-old Dane was also blamed for goals conceded in subsequent games against Manchester United and Manchester City.
