Lazio fullback Aleksandar Kolarov admits he's flattered by interest from Liverpool.

Liverpool are tracking the Serbia international left-back ahead of the summer market.

And Kolarov said last night: "Every day I learn from the newspapers that several clubs are interested in me. The interest of Real Madrid, Liverpool and Inter Milan can only flatter me, but so far there is nothing concrete.

"Now I think of only keeping Lazio up."
