And the Spaniard says it is up to billionaire owner Sheikh Mansour and his right hand man, club chairman Khaldoon Al Mubarak, to decide at the end of the season to sack him or back him.
Manchester City face Arsenal in the semi-final at Wembley on Sunday having dropped out of the Premier League title race earlier this month – they are 11 points adrift of leaders Chelsea – while they made an unexpected last 16 exit from the Champions League and went out of the League Cup at the fourth round stage.
It leaves Guardiola needing to win the FA Cup to preserve his record of winning a trophy in each of his previous seven seasons as a manager, four at Barcelona and three at Bayern Munich.
Guardiola is happy with City’s development this season but asked if the owners will share his view he said “I don’t think they will be happy. The expectations of the club are as high as possible and are to win all the titles and we were not able to do that.
“So if they are not happy I can completely understand. And we could have done better in terms of the results and even in the way we played because we wanted to be in title the race and Champions League until the end.
“Despite the fact that I am happy with what we’ve done, it is still not enough.

“But they have to decide. They are my bosses. The chairman and the owner have to decide whatever they want. “
Guardiola says quite apart from his own pride and reputation, winning the FA Cup is important for his players’ collective belief that his methods and philosophy are taking them forward.
"It is important to achieve a final,” he added. “I would like [to win] the FA Cup so my players realise how good they are. For all clubs titles are important. Winning titles gives you the self-confidence to say ‘we’re good enough to compete.’
“When you win, the next time it will be a little easier. This is a fantastic club and team, I’m so proud of what we’ve done and how we’ve overcome bad moments."
Guardiola delivered good and bad news on injuries ahead of the game. Gabriel Jesus, out for just over two months with a fractured metatarsal, will travel with the squad and the Brazilian youngster could figure from the bench.
But defender John Stones is ruled out with a muscle injury and is a doubt for the Manchester derby next Thursday.

Gabriel Jesus could return for Manchester City against Arsenal
"Gabriel’s really, really much, much better,” he said. “Today he will take part in training with us. He's coming back with his happiness and we are so happy he's back again.
"We are going to travel with all the squad to Wembley, all the group, and he will be part of that. After that, we will see.
“Of all the players who are injured I am happy when they come back but especially for him. He had all the European clubs in his hands and he came here to join us.
“We cannot forget that. I am so happy he joined us here. He arrived and suddenly can play after just two or three weeks. That’s why we’re so happy he can help us to score goals at the end of the season.”
Guardiola says he will make a decision on Jesus tomorrow evening.
"All the squad are travelling down tomorrow and we will watch the match between Tottenham and Chelsea in the hotel," he said. "After dinner I will decide the team."
He is hoping Stones may have recovered in time for next Thursday's re-arranged Manchester derby at the Etihad Stadium.
"Stones has a muscular injury. It happened one day in a training session. Maybe he come back for United, but I don't know."
