"I can imagine the fans are scared. They saw last year and the first home match. They have to believe. Paul Scholes (who said he is genuinely scared for the club's future) has to believe."

Liverpool manager Brendan Rodgers has been talking at a news conference about his side having a £16m bid accepted for AC Milan striker Mario Balotelli.

"We understand that sometimes you have to take a risk with people and normally, a lot of the time, if you take that risk you can get a reward for it," said Rodgers. "We've always said we were looking for another striker.

"We have quite an extensive code of conduct for both staff and players and we have a fantastic environment here. Over the last two years that has been something very important to create and there will be nothing that will shake that."
