Liverpool boss Brendan Rodgers is delighted with the form of Martin Skrtel.
Rodgers admits speaking with the defender about his future last summer.
He told liverpoolfc.com: "With Kolo (Toure) going out and him going in, it is incredible credit to him for how professional he has been. He has never moaned once despite lots of speculation about him going here, there and everywhere.
"He and I have spoken a number of times, he knows where he has been at - he has never moaned or groaned. He has just got on with his work, done extra work so when that time came he was going to be ready.
"He was absolutely brilliant against Manchester United. It doesn't give me a problem, it just gives me a nice problem to think about. That's my job as the manager."
