The "Blue Lions" Chelsea will go to Old Trafford to challenge the "Red Devils" Manchester United in the fifth round of this season's Premier League. Maresca said at the press conference that the 18-year-old Esteban William is capable of playing in different offensive positions and hopes that the young winger will spend more time to realize his potential.

Chelsea drew 2-2 with Brentford in the last round of the league, thanks to goals from Palmer and Caicedo. With an unbeaten run of two wins and two draws in the last four games, Chelsea currently sits fifth in the standings with eight points.

In addition, Esteban Willian, the young winger who joined Chelsea in August, has demonstrated his strength through the game, including assisting Enzo to score in the previous game against West Ham.

Chelsea manager Maresca said, "Estevan William can play in all attacking positions because he is very talented and an outstanding player. But at the same time he is only 18 years old, so it will take some time. But I think both Estevan William and Palmer can play as wingers and can also be competent as No. 10. I feel very lucky to have them at the same time."

In addition, Manchester United, coached by Amorim, lost 0-3 to Manchester City in the last round of the Manchester derby and failed to get 3 points.

Speaking of Manchester United manager Amorim, Maresca said, "I admire Amorim very much. I have been following him since he coached Sporting CP. He is an excellent coach. Like all coaches, when starting a new project, there may be difficulties, big and small, but I have no doubt that he is an excellent coach."

"I think it's always difficult to play against Manchester United at Old Trafford. Now is not the right time, nor was it next year or last year. Manchester United are a strong team and it's a difficult away game. I've watched their games this season and some of the results don't fully reflect what was there."

Maresca continued, "Even in the derby against Manchester City, before 0-1 or 0-2, they were still in the competition. When the score was 0-0, they even had several chances to take the lead. So there is no doubt that it will be a tough game."
