Transcript: "Where has the game of soccer changed most dramatically over the last decade? I think the pattern that has changed the most is the speed of the game, which in turn has altered the speed of the players. Players have had to get faster, more powerful because of the speed of the game increasing. I also think this is going to increase again over the next few years. We're going to see more football actions throughout a game, and that's going to be increased dramatically, which is going to put even more physical demands on the players, which increases the demand on the players' bodies and also underlines the importance of a player's strength and their conditioning so they are ready to deal with the demands of the game. I can only see it getting quicker over the next few years. We'll see what happens."
