Tello - he's getting games at Barcelona, why would he leave?
Krasic - He's class, one of the best right wingers around, so sign him up
Sigurdsson - average, so not good enough
Dempsey - he's just had his best season, so he'll be a waste. Anyway, you won't win a title with Dempsey in the team
Kalou - utter genious. Sign him up Rodgers!!!]
Tello has just one year left on his contract, and he is starting in place of injured Villa, and he still has Sanchaze and Pedro to compet with.
Sigurdsson is rated by Rodgers, and he knows him best.
Krasic is crap according to who regularly watch Juventus, he is like their Downing, some say worse
Dempsey is going to be 30 next year, he will still be at that point between great expereanc and physical shape, good for at least 2 years. For 4.7m it is not bad
Kalou has great skill, but is a " hot/cold" kind of player
