The 26-year-old midfielder signed a contract extension last month which will keep him at the club until 2030 and the sportsman felt he owed it to the Hammers to stick around because of how much he’s progressed there.
He told Match magazine: “West Ham gave me the opportunity and I wouldn’t be an England international without them!
“It’s only right for me to pledge my future and my career there.
“I was happy to get it all done.
“It was stressful, but now I’m here and I’m happy.”
Jarrod doesn’t think he’s ever played better football.
He said: “I think the way I’ve started this season, I’m probably playing the best football in my career!
“I’m getting better and contributing to the team.
“I’ve got a more mature head on my shoulders and I feel in a really good place.
“I take momentum and confidence from each game and just want to keep playing with a smile on my face.”
And the sportsman is grateful for the support of West Ham boss David Moyes.
He said: “David Moyes has shown faith in me by playing me.
“For me, it’s just about repaying the manager’s faith for bringing me to the club in the first place and then helping me learn on and off the pitch.
“He has been great for my development.”
