The defender has been linked with Napoli this week.
He told Liverpoolfc.com: "I think it's always good when there is competition for places and it's very important for your performance.
"The manager will decide who is in the best form and start that player. I'll do my best and all I can to make sure that I'm the one he's going to be starting with.
"Kolo is a great player. He's a very experienced player and he has been playing in the Premier League for a while.
"Throughout the five or six weeks he has been with us, he has shown that he is a quality player. He came in to play the same position as me, so we'll see who is going to start.
"Of course I will try to improve this season because I missed the second part of last season. I tried to do my best in the pre-season and show the manager I am able to play, so we'll see how it goes this season.
"I'm ready. I was ready before and I'll always be ready. Then it's up to the manager who is going to start. I will try and I will give my all to get into the team."
