Andre Villas-Boas admits he is under increasing pressure following Chelsea's 1-0 defeat at West Bromwich Albion, but the beleaguered manager remains determined to save his job.
Gareth McAuley's late goal condemned Chelsea to a shock loss at The Hawthorns yesterday to leave Villas-Boas' Blues future hanging by a slender thread.
The west London club have won just one of their last seven matches and only three from their last 12 in the Premier League, leaving them three points adrift of fourth-placed Arsenal in the race for the final UEFA Champions League spot.
"Will this result increase pressure on me? You have to agree with it," Villas-Boas said. "We are in the same position, fifth, but we are now three points behind Arsenal. It is a big, big disappointment. Every defeat Chelsea suffers piles more pressure on any manager.
"Today is acceptable that pressure piles on a bit more. We have responsibilities to the fans and the club and we did not perform." Villas-Boas insists he remains the man to lead Chelsea forward, adding: "If I didn't believe that I wasn't then I would not have come."
But he was less than impressed with the display of his players, conceding the best side won at The Hawthorns. "Full credit to West Brom for playing a magnificent game. We just weren't good enough on the day," he said.
"They won every first ball, every second ball. They were far superior than us. It was a big, big disappointment. Everybody must do better - players, staff and manager, for sure."
Baggies head coach Roy Hodgson was thrilled with his team's display as they recorded a third successive victory and moved up to ninth position.
"We did play very well. As a team, we can feel very proud of our performance. In my opinion, it wasn't a poor performance from Chelsea, it was a good one from us," he said.
Hodgson, who endured similar pressure at Liverpool last season, believes Villas-Boas deserves time to turn things around.
"I sympathise and empathise with Andre but the day we coaches, who realise football has two sides to its coin, don't stand up for each other will be a sad day for football," he said.
"He doesn't need advice. He is a very successful manager. I saw the Porto side play the other night at Manchester City and that is the team he put together. He has come to Chelsea with high expectations and it has not started as well as he would have liked.
"But it is early days. To build a team takes time and there are no magic wands. If he is going to be successful, he will need time to stamp his authority on the team and given time, he will be able to do that."
