Chelsea defender David Luiz claims a combination of maturity, belief and working with different coaches is responsible for the improvement in his game.
Eyebrows were raised when Antonio Conte brought the Brazilian back to Stamford Bridge for a second spell in the summer of 2016.
While his qualities as a ball-playing centre-half were never in question, his focus and composure were after a previous stint in London which saw him famously branded a ‘PlayStation’ footballer.
Luiz has, however, thrived as part of a 3-4-3 system and considers himself to be a better player at the age of 30 than he was first time around.
Asked by Sky Sports if he has matured, Luiz said: "You have to, and also as a person. I think the experience gives you many things, and yes, as a person and a footballer, you have to if you want to learn. If you are open every day.
"I read more of the game now, I can understand more of the game, it is a different pressure now with the big games. Many, many things. I think if you want to improve, you need to think you are a better player than you were.
"I've worked with six, seven, eight coaches, they have improved my game, different leagues and different countries."
Luiz ended up spending just two years away from Chelsea at Paris Saint-Germain, so the transition back to Premier League life has not been all that difficult.
Pressed on whether the English top-flight had changed in away way during his stint in France, he added: "I think the intensity is the same, I think the level is the same, because it is always six, or seven teams fighting for the title. I don't see a lot of difference.
"It continues with the high credibility, it is one of the best leagues in the world, if not the best, and it is difficult to win."
Luiz and Chelsea look set to be crowned Premier League champions this season, with West Ham’s 1-0 victory over Tottenham on Friday meaning that Conte’s men can pull seven points clear at the summit by seeing off Middlesbrough on Monday.
