Babel, the £11.5million winger from Ajax, has only started five matches this season but he said: "It's something different for me but it is not an issue.
"Everyone knows the boss likes to change line-ups and tactics depending on who we are playing. But I understand why he does it.
"You cannot play the same way in every match and you can't use the same players all the time. Flexibility is vital.
"It is an important part of the game and even more so here in England where teams play in four competitions. It is unrealistic to expect every player to play week in week out.
"It is similar to when the boss switches the wingers in games. Sometimes I play on the left and it doesn't work, so making changes can help both wingers.
"It gives the team an unpredictability and that has to be good. It means the opposition are not quite sure about what you are going to do and that gives them problems because they're left guessing."
