The Hammers have lost all of their opening three matches of the season.
“In football you always need patience,” said Grant.
“I am a long-term person and if you see my clubs before – even at Portsmouth and Chelsea, you see developing teams, they develop every match and you will also see the same here.
“We need not to think about one week or two weeks but longer.
“The most important thing about the table is the end of the season, not now,” he added.
“The teams that are in the second or fourth place in the league will not be there and I can guarantee that some teams that are at the bottom of the league will not be there at the end and I’m sure we will be one of them.”
“I’m enjoying the challenge here,” added the 55-year-old.
“I am enjoying it because it is a big challenge, a good club and our vision is good and if we do the things we want to do here over the next few years then West Ham will be a good team.”
