The midfielder also believes that signings were necessary so the club could keep up with their rivals.
The former Croatia and Besiktas boss was brought in as Sam Allardyce’s replacement last month with the remit of bringing a more entertaining style of football to Upton Park.
That has already been seen to some degree, with two comfortable victories over FC Lusitans in their Europa League first qualifying round tie, while they also enjoyed an entertaining 3-3 draw with Peterborough United on Saturday afternoon.
Noble is one of the longer serving members of the West Ham midfield and has seen several managers at the club during his time, and he is full of praise for his new boss despite their short time together so far.
“He’s been fantastic up until now,” he told whufc.com.
“Slaven is an approachable man and he has made it clear that we can approach him. It’s still pre-season so it’s not normally well into the season that you see the real character of the manager.”
West Ham need to spend money to compete
The Hammers have been busy this summer, with several new faces already arriving at Upton Park to bolster Bilic’s squad.
Goalkeeper Darren Randolph joined on a free transfer, while the likes of Stephen Hendrie, Pedro Obiang, Dimitri Payet, and latest recruit Angelo Ogbonna have all been secured as well, with only Hendrie arriving for a relatively small fee.
The capture of Ogbonna in particular looks to be a decent one, as they fought off interest from elsewhere for his signature, and Noble says the club need to spend money in order to compete with their Premier League rivals.
“I’m pleased with the investment made and we need to as it’s a big season for us,” he added.
“We need to spend money to compete with the rest of the teams. We’ve brought Dimitri, Angelo and Pedro in and we need to now gel together on Monday and push on from there.”
