Reid penned a new six-and-a-half-year deal with the Hammers at the start of the month, but is expecting to have to be patient before the club can break into the top-six.
West Ham's co-chairmen David Sullivan and David Gold have both commented on their desire to help the London club become Champions League contenders in the Daily Mail, but Reid thinks that the process will be a long one.
“It won’t take only one or two years - it might be after I finish that the club gets into the top six or top four," he said.
Reid reportedly turned down interest from Tottenham Hotspur and Arsenal to stay with West Ham and he revealed the reason behind his decision today.
“It did strike me to move to another place, but my family and I wanted to stay here,” Reid said.
“I figured out what I wanted to do with my career and that’s be part of the place here and help the club to improve."
For the Hammers to have Reid's future secured is a major boost, as he has become one of their key players and one of the best defenders in the Premier League.
The New Zealand international is composed in possession, but he is also a solid defender and is the standard of player that West Ham will need to fill their squad with if they are to meet their ambitious targets.
Reid has joined the likes of Mark Noble and James Tomkins by signing a new contract at the Boleyn Ground, with West Ham looking to create a settled squad for the future.
