The French striker signed for Everton this week from Brighton.
“I have met almost all of them and I knew most of them, obviously from playing against them," he told evertontv. “It's funny - they made some jokes with me saying like, 'We hated you but now you're one of us so we'll love you!'
“It seems like the group is doing really well together. I'm excited to get back on the pitch and get to work.
“It's just my nature — when I do something I do it at 100 per cent. When I play for a club, for a manager, for my teammates, the fans, I am ready to do anything at hand to help the club to win. That's just who I am.
“When I step on the pitch, I will run, I will tackle, I will make assists, goals… Whatever the team needs, I will do it, because I want to be successful and I want my team to win.
“You can have ups and downs but we all need to give everything and I think that's what I bring to the team... I will fight."
Speaking at his pre-match press conference on Friday, manager Frank Lampard reiterated his desire to reinforce his attacking options.
Maupay's arrival was sealed hours later and, while ineligible for Saturday's trip to former club Brentford, the new Blues forward says he is raring to go after making the “easy decision" to join Lampard on Merseyside.
“It feels amazing — I'm just so happy to be here," Maupay explains. “Everton is a big, big club, with very good players and unbelievable fans.
“The manager, too. He has been an unbelievable footballer, obviously, he is an England legend. To have a chat with him and for him to tell me, 'I know you, I know what you can bring to the team and we need someone like you in the team', meant a lot to me.
“It just felt natural for me and it was a simple decision.
“For me, I knew straight away I wanted to play for Everton and help the club to succeed in this league.
“I haven't played the first three games of the season but I've been training really hard, I'm fresh and I just can't wait to get started."
