Liverpool isn't looking to sell Suarez. We have no reason to - if he has another stormer this season, his value will not have depreciated significantly, and he can still be sold next year.
He isn't in control of his future, the club is. He's got 3 years on his contract and there's no buyout clause. If the club got a huge offer for him, then we'd sell, but if the offer isn't ridiculous then we have no cause to sell. That is why Liverpool fans expect a big fee for him.
He can talk about wanting to move but at the end of the day, it's not up to him, and he's already proved that he isn't going to sulk and moan until he gets moved on. He showed up for training and even stayed up to welcome home the rest of the team who arrived in Australia late, and trained at 100%, scoring in the 11 v 11 session in Melbourne.
