The Hammers welcomed their new manager at the London Stadium with a 3-2 success over Fulham.
While Potter knows there are areas to improve, he was so pleased at the players’ application so soon after his arrival.
He stated: “Three points, a very, very committed performance. It wasn’t perfect, of course, but the attitude and the effort and the willingness to fight for each other was certainly there.
“It's a great foundation for us to build on. We can improve on lots of things, but I'm delighted with the three points.
“Credit to Fulham - they started well and we couldn't quite get the pressure on.
“We ended up a little bit passive. I think we needed to get the crowd (up) and we needed to get more into some duels and some contact with them.
“So we moved Mo (Kudus) a little bit up and he helped us. Aaron (Wan-Bissaka) was more aggressive. Konstantinos (Mavropanos) was aggressive.
“So they were really, really good, and I think that helped us get a couple of goals in the first half. That was a nice foundation to start the game as well.
“There was lot of work to do in the second half but, yeah, we're just really happy.”
