Manchester United boss Louis van Gaal says three full seasons are needed for the Red Devils to achieve set objectives.
The Dutchman was criticised by the media after the mid-week exit at the hands of Middlesbrough in the League Cup.
But he says his team is improving and he is ready to do everything for the club and fans.
"I usually use Dutch expressions, but you have one here: 'Sticks and stones may break my bones, but names will never hurt me'. Fantastic expression!" van Gaal told reporters.
"I know that if I lose and lose then I will be finished, I know that. But I shall do everything for this club and these fans, who are unbelievable.
"Last year we had 13 points from 10 games and now these fans see that we have 20 points out of ten and that we were in the next round of the Capital One Cup [compared to last season] and we are in the Champions League.
"Last year it was not like this. Last year we had 15 injuries. Okay, after Wednesday's game we have more injuries, but we had three at the most [before that].
"We are improving a lot, but it is a process, it takes three years, which is why I signed for three years."
