awais007 9 years ago Chelsea, Pakistan 178 922 Rafa Benitez remained defiant in the face of continued fans' protests against his appointment at Chelsea - but admitted that the size of his challenge at the club is greater than he had imagined after the European champions slumped to a 3-1 defeat at West Ham. Chelsea are without a win in seven Barclays Premier League games while Benitez has collected just two points from his first three fixtures. Chelsea fans again abused their new manager, displaying banners in support of sacked boss Roberto di Matteo and calling for Benitez to go. But the Spaniard insisted he would remain unaffected by the ongoing hostility. 'We know that we have to win games to change things around,' said Benitez. 'My concern is to improve the team to analyse what is wrong on the pitch. If we improve the team and start winning, it will be easy to turn things around. 'We have to improve on the pitch and the fans will be happy. If we improve on the pitch it will be easier for everyone.' At the moment, though, Chelsea are suffering their worst League start in the Roman Abramovich era - 26 points from 15 games. Their run of seven Premier League games without a win is their longest in the top flight since February 1995, when they went 10 games without victory. Benitez did concede that the task of saving Chelsea's season is more difficult than he envisaged. Asked if the job was a tougher challenge than expected, Benitez said: 'It could be . . . in terms of this being a top side and it being the middle of the season and obviously the results were not the best.' Chelsea led through a Juan Mata goal but were then stunned by a second-half West Ham comeback and goals from Carlton Cole, Mohamed Diame and Modibo Maiga, leaving Benitez perplexed at his team'scapulation 'It's difficult to explain when you are so good in the first half,' he added. 'How can you not manage in the second half? 'Everyone has seen in the first half that we could have scored two or three goals and finished the game. But we didn't do it. We were giving the ball away easily, not winning first balls, seconds balls, not comfortable in possession. 'We had been a bit better in defence, with two clean sheets, and today we were a lot better in attack. Now we have this situation in defence where we have to improve again.' He does not expect the fans' backlash to affect his players. 'I hope that would not be the situation,' he added. 'Why? Because we have experienced players, so they know that they have to manage and cope.' Asked if the negativity and bad results might even end his seven-month interim appointment, Benitez insisted: 'Again I would say it depends on things that we can do on the pitch. We improve on the pitch it will be easier for everyone.'
