Liverpool's Jamie Carragher insists that the continued speculation over the future of boss Rafael Benitez is not unsettling the players.And the 29 year-old local hero maintains that new owners Tom Hicks and George Gillett should not have to keep saying 'everything is fine, every few minutes' just to answer speculation. Carragher said: 'The situation over the manager doesn't affect me, it doesn't affect the other players, we get paid to play football and that is what we have to do. 'Our objective is to improve on the way we have played in the last few weeks, we should not be getting involved in things like that off the field, we have got to look after ourselves. 'We have to stick together. At the moment we are getting a lot of criticism from a lot of people, but we must rally round, get together, and prove a few things out on the pitch. 'The last few weeks have not gone as well as well all would have liked but the main thing is what goes on out on the pitch, not off it. 'We should do what we are paid to do. We should concentrate on that.' Benitez has been the centre of another week of extraordinary rumour and speculation after media headlines ahead of last Sunday's FA Cup draw at cash-strapped Luton suggested he knew he would be sacked in the summer. The Spaniard has since denied in the local Liverpool media that he has ever briefed journalists 'off the record' that he anticipated the axe, as was implied. That reaction from Benitez only came after it became clear that Hicks and Gillett expressed astonishment from New York - ahead of a key Liverpool board meeting - that their manager had seemingly rocked the boat yet again. It was also suggested that the Reds players at Kenilworth Road had become unsettled by the continued controversy surrounding their manager. And the fact that Hicks and Gillett have steadfastly not given Benitez a vote of confidence has also become a growing concern. But Carragher, who was captain in the 1-1 draw at Luton, said in an interview on Sky Sports: 'It's up to the owners what they say about the manager, it is nothing to do with me what goes on between the manager and the owners. 'A few months ago they said everything was fine, I don't think they should be coming out every few minutes answering speculation. 'As for us we are here to play football, that's our job and the rest is nothing to do with us.' Benitez upset the American owners last year by being critical of the club's transfer funds and policy, and when Hicks and Gillett believed that the Spaniard was suggesting he was a 'lame duck' manager, questions were asked again. But Carragher refused to be drawn into the debate, and preferred to concentrate on Liverpool's task for the rest of a disjointed campaign, with Saturday's trip to Middlesbrough another 'must-win' game for the Merseysiders if they want to stay in contact with the Premier League leaders. Carragher was predictably upbeat, claiming: 'We are still in the FA Cup and we still have a really big tie with Inter Milan soon in the Champions League, and everyone knows how good we can be in that competition. 'We are disappointed we have fallen away a little in the Premier League but we are still only halfway through so there's a long way to go even it is fair to say we are outsiders now. 'We still want to make a challenge, but we are not kidding anyone because we know it will be difficult. It's not just the points difference but there are three other big teams ahead of us at the moment. 'There is no point throwing the towel in, we will just keep going.' Liverpool hope to unveil new defender Martin Skrtel, a £6.5million signing from Zenit St Petersburg tomorrow. Chief executive Rick Parry, who has just returned from the New York meeting, held final discussions with the Slovakian international's representative today. And it also seems likely that midfielder Mohamed Sissoko is on the brink of a £10million move to Juventus, which will give Benitez extra funds to try to complete the permanent deal for Javier Mascherano. Sissoko has fallen out of favour at Anfield, and told Radio Montecarlo: 'I'm still a Liverpool player, but I expect a big announcement in the next few days. 'My agent, Juve and Liverpool are working on my departure. Everyone is asking me whether I have already signed. I haven't yet but my move to Juventus is very close. 'I'm expecting the good news any moment now, but I'm enthusiastic about beginning a new adventure in Italy with the Bianconeri.' Sissoko is expected to leave on a loan deal, with Juve being given the option to buy him at the end of the season.
