Enzo Mariska, the head coach of Chelsea FC, expressed his great happiness with the performance of young star Estefao, after his brilliance in the team's 5-1 victory over Ajax in the UEFA Champions League, affirming that he feels proud to coach a player with such talent.

Mariska said: "I feel very lucky to be his coach; he is an exciting player, and we can enjoy watching him. The fans pay for tickets to see players like Cole Palmer and Estefao, and it's great to have players with such qualities."

The Italian coach added: "I work with the young players every day, and I know what they can do. There will definitely be moments when we struggle a little, but the good thing about them is that they want to develop, and I think that's wonderful. With Estefao, there is no need to worry; he is very humble and polite, and he always has his family by his side."

Mariska spoke about the importance of maintaining momentum after the big victory, saying: "We must continue on this path, knowing that facing Sunderland will be difficult. We will try to prepare with the same intention we started with on day one, which is to win the match, and then we will see what happens."

The Chelsea coach concluded his remarks about the team's future and the youth, saying: "This is the club's strategy; we have many young players, and we were the youngest team in the history of the Premier League last season. We continue in the same way this season. We made 10 changes tonight, and it wasn't easy, but it was a special night for the club, especially after three teenage players scored goals. I am very proud of them; it was a special night for these young players and for Chelsea."
