Former Chelsea captain and coach Gianfranco Zola has urged the club's young players not to fear any big name arrival.
As soon as the club's 12-month transfer ban was lifted, prolific Germany striker Timo Werner arrived from RB Leipzig for £53million and Hakim Ziyech completed a £38m move from Ajax.
But rather than fear the competition for places, they should embrace their new team-mates and learn from them. That is the view of Blues legend Gianfranco Zola, who had arguably the greatest mentor for a young, creative player in the late 1980s.
"I would have not been the player I was if I didn't train with Diego Maradona," he explains, having been at Napoli with the Argentina great between 1989 and 1991.
"He was so influential on every aspect of my game. I promise you — I would have been another Gianfranco Zola if I hadn't trained and played with Maradona every day."
He also told the Daily Mail: "I don't think John Terry would have been the player he was if he hadn't had Marcel Desailly or Frank Leboeuf in front of him with us at Chelsea."
