Rob Green has revealed how Cesar Azpilicueta struggled to deal with Callum Hudson-Odoi during Chelsea training sessions.
England ace Hudson-Odoi has impressed whenever he has been called upon the Blues' first team, with the winger making four appearances in all competitions so far this season.
Although he has seen his game time restricted since breaking through as a 16-year-old due to an Achilles injury and Maurizio Sarri's regular failure to play him.
And Sarri's seeming lack of trust of Hudson-Odoi, who put in a transfer request to join Bayern Munich, is even more confusing after ex-keeper Green admitted how the academy graduate made his experienced teammates looks silly in training.
"We had Willian, Pedro and obviously Eden [Hazard] in the same positions but the manager had such a strong belief about playing the players he trusted. He would not play other players," Green told BBC Radio 5 live.
"It was the same team, the same formation every week, maybe one or two changes and Callum just wouldn’t get a look-in.
"We’d go into training and he’d tear it up day in, day out and the things he would try in training with no pressure… and he’d do it in games. You’d just see him trying stuff because he just wanted to.
"It’s not that players like this don’t care. It’s just that they can play with the freedom and understanding that they can try these things and are good enough to pull them off.
"He would try it in training against some of the best players in the world, some of the best defenders.
"Azpilicueta playing up against him in training… couldn’t live with him! He’d chop inside him and Azpi would turn around and go, 'Oh God, he’s gone past me', and then he’d just bend one in the far top corner or fire one in at the near post."
