Alonso has started five consecutive Blues games, stepping in and up to the challenge after Ben Chilwell's knee injury.
"It's obviously never nice to see a team-mate injured and that's the most important thing," the 30-year-old told the club's website.
"When you don't play games, it's always tough but trying to help the team win games is our main job."
"I just try to listen to what the manager wants and what the opponent requires and try to help the team as much as I can.
"It's important to adapt and find solutions to different challenges during a game or depending on who we play against. It's good to have different options and try to have different ways to cause problems to the opponent."
