West Ham 1-5 Chelsea: Teenager Estevao Willian shows promise in Cole Palmer absence

Estevao chose Chelsea despite interest from many of Europe’s leading clubs, including Bayern Munich, Paris St-Germain and Manchester City.

He fits the classic “wonderkid” characterisation to a tee, joining the Blues off the back of much hype and tipped to achieve great things.

Estevao gave a glimpse of his talent in the Club World Cup, where he scored in the quarter-finals as former club Palmeiras lost to Chelsea, and first impressions of him in England have been positive.

“I think he’s young but he showed that he’s very mature,” said Chelsea team-mate Marc Cucurella.

“He made very good decisions and all the new players, all the new signings came here to help the team, to bring something good, good energy, good talent. I think we have an amazing squad, so I hope we can do good things this season.”

Former England and Chelsea goalkeeper Rob Green added that, for Estevao, it looked like it was “just a joy to play and go out there and express yourself”.

“It looked like he played where the shirt didn’t weigh anything and there was no expectation,” he told Sky Sports.

“There’s a real freedom and a brilliant thing, having had time at Chelsea, you play with so many international players and the different ways they approach the game, going into the game, on the team bus.

“Brazilian players, it’s like it’s a party. It’s there to be enjoyed. Let’s go and play football, the excitement’s there, let’s go and enjoy it.”
