The striker joined earlier this month and scored his first goal on Tuesday.
The England under-21 striker joined the Hammers earlier this month after his contract at Manchester United expired.
He opened his account for the club on Tuesday as he linked up with fellow new signing Domingos Quina to score in the draw with FC Slovacko.
It was a positive start to life with Slaven Bilic’s side for the striker, and he says that he has suggested that he is settling in very well since his move.
“I’ve loved every minute,” he told whufc.com.
“Everyone has welcomed me with open arms and I am delighted to be at West Ham. The senior players have helped me to settle in. We have a great group here and hopefully we’ll kick on.”
The striker now says that his main aim is to continue putting in positive performances and trying to make the breakthrough into the first-team in future.
He is certainly at the right club to do so, with manager Slaven Bilic having shown his willingness to give youth a chance when he handed Reece Oxford his debut last season.
In a team that is short on quality strikers, there is every chance he could break through and Fletcher admits it will be vital he keeps showing he can do it to earn that chance.
“My aim has to be to break into the team,” he added. “It’s a very talented team and one that is going to be competing at the top of the Premier League, so for me it will be vital to keep showing myself I can do it.”
