Chelsea boss Carlo Ancelotti says he shapes his tactics to best suit his players.
Ancelotti, who also played for 18 years before becoming a coach, claims that Chelsea's powerful attacking style of play comes from his time when he coached Zinedine Zidane at Juventus.
The Italian says he had to abandon his usual tactics and adopt a diamond formation, typically 4-1-2-1-2, that would give Zidane the freedom to show what he could do.
"Before, when I started to train, I had an identity which I put on my teams," said Ancelotti said.
"I didn't look at the characteristics of my players. I wanted to play 4-4-2 for the first two years. After that, I changed my ideas. It changed at Juventus - Zidane didn't want to play on the left, but in the centre, so I changed my formation for my players.
"There is not a winning shape: you can play 4-4-2, 4-3-1-2. Now I look at the skills and characteristics of my players and put the right shape in the team for them."
