The Blues fought back from three goals down against West Bromwich Albion to claim a 3-3 draw on Saturday.
"I think you can see how good the spirit is here," Hudson-Odoi told the club's website. "All the new boys that have come into the squad have gelled really well.
"They are improving us as a side, they've all been working really hard in training and they show out on the pitch that they are quality players.
"We all have the right mentality and the right spirit to go on and win games. The start wasn't the best, we know that, but we showed what we are all about by turning the game around and leaving with a point.
"The new players have played their part and they've come in and bought into the mentality that we have at this club."
