Moisés Caicedo's brilliant volley helped Chelsea beat Ruben Amorim's AC Milan 3-0 in a preseason friendly on Saturday.
Caicedo struck with the outside of his boot, meeting a corner from Romeo Lavia, for the pick of goals in Indonesia.
Caicedo had set up the opener from a corner which João Pedro headed home in first-half added time. Joao Pedro added a second a minute into the second half before Caicedo sweetly scored the third in the 50th minute.
"We want to be versatile in our approach and system," Xabi Alonso said. "I think we have the players to adapt to different ones because they understand how to support each other.
"The principles are the same but the movements can change; we need to be unpredictable, we want to be flexible, and we want to have a threat. The system is just a picture; you need to move, rotate and create dynamics [in the team] and that is when the picture becomes a movie.
"We are not just sticking to one idea and the more options that we have, the better team we will be."
Alonso added: "In pre-season, we have a few games already and for sure, the more players we have available, the more options we have.
"I think that we will get better and by the start of the Premier League season we will be ready. But even that will be another starting point in the evolution of the team. So it will be a process that takes months and in every game."
Mykhailo Mudryk, Estêvão and Reggie Watson were among the players who gained some minutes for Alonso's side, while Danny Welbeck and Marco Palestra started. Geovany Quenda and Nicolas Jackson came on and hit the woodwork.
Luka Modric, Ruben Loftus-Cheek, Rafael Leão and Gonçalo Ramos played for Milan, for whom Amorim was in the dugout in his first role since being sacked by Manchester United.
Chelsea had previously lost preseason games to Tottenham and Juventus before this much-needed performance.
Chelsea continued their preseason on Sunday against Malaysian champions Johor Darul Ta'zim before their Premier League campaign begins against Fulham on August 24.
