Gianfranco Zola believes Cole Palmer is a "top player", though he has been surprised by the impact the England international has had since joining Chelsea.

Palmer signed for the Blues at the start of last season and is a hugely influential figure at Stamford Bridge.

He was named the Premier League's Young Player of the Year, and since his debut in September 2023, Palmer has been involved in 44 top-flight goals (28 goals, 16 assists). No other player in the competition has directly contributed to as many goals in that time.

Already this season, he has netted six goals and registered five assists in the league, the most of any Chelsea player, and made history against Brighton, becoming the first player to score four times in the first half of a Premier League match.

And Chelsea great Zola has high hopes for the 22-year-old.

"At the moment he is producing performances and results worthy of a top player, so where he can get, I don't know, because this guy has surprised everyone, especially me," Zola told Stats Perform at Festival dello Sport in Trento, Italy.

"I knew he had good qualities, but doing what he is doing is a surprise for me. And so, I would really like him to continue to surprise both me and the others, so let's hope he continues like this."

Palmer again ole ole.

Chelsea sit fourth in the Premier League and are unbeaten in the competition since their opening-day loss to Palmer's former club Manchester City.

Enzo Maresca is now looking to become only the fifth boss to win each of his first four Premier League away games, with one of the previous four to do so being his next opponent, Liverpool's Arne Slot.

Despite questions surrounding the club before the start of the season, Maresca has seemingly imposed his style of play on the squad quickly, and Zola is impressed with how they have adapted to life under the new head coach.

"I am very happy because beyond the results, which are positive, the team is showing signs of being on the right path," he added.

"There is a structure that is working and then, as they say in England, a 'top of that', that is Palmer, who is continuing to do extraordinary things as he did last year."

Chelsea face league leaders Liverpool on Sunday and will be looking to stay in the mix at the top of the table by claiming their first win in seven against the Reds.

Maresca has shrugged off early suggestions that Chelsea could challenge for the title this season, and though Zola thinks the Blues are competing well, he expects it to be tight in the Premier League.

"Undoubtedly the competition is very strong, very high," he said.

"Liverpool, Arsenal, who have been doing important things for a few years now, City, who will return to their levels, are already at their levels, have had the misfortune of losing a very important player like Rodri, who can be a factor, but [Pep] Guardiola has always shown that he can find solutions, so they will also be there.

"The Premier League is competitive, and Chelsea will have a lot of competitiveness against these teams. However, I repeat, it is encouraging because they are growing well."
