Danh ngôn của Petr Cech (Sứ mệnh: 6)

It's normal in a top club that people change.
Once you're on the pitch, you play for your team, and you want to win. During the year, you can play against friends - you can play against big friends and close friends - but once you are on the pitch, this friendship goes away, and you just focus on winning the game.
