Trinidadian international Brent came over on a six month loan period from Levski Sofia in Bulgaria, but, although he made some impressive performances in the reserves, he was allowed to move on when the transfer window opened in January.
"I am enjoying it and the most important thing is that I am playing again, because I didn't think I could play reserve football for too long," he says.
"I was thankful to West Ham that they gave me the opportunity to be among their set-up, but I had to move on."
Brent's first stop was Luton, where he went on trial, but that didn't work out.
"I guess they were looking for more of a defensive midfielder rather than what I was offering, which was a bit of creativity," he says.
"So I am at Northampton to the end of the season; hopefully I can help them stay up, score a few goals, and see what happens then."
He hopes that the Hammers can pull themselves clear of the problems they are having and adds: "I am still in touch with Izzie Iriekpen, Jermain Defoe, and a few others.
"I wish them all the best and I hope things turn around for them; I think they can, but at this point they have to get it right."
Brent, who has scored one goal in four games, is likely to be joined at Northampton by Izzie going there on loan when he recovers from a hamstring injury in the next week.
