Amad struck a superb equaliser for Saturday's 2-2 draw at Nottingham Forest.
And his partnership with Mbeumo has been one of the big talking points from United's early season turnaround.
Amad said: “I think we have a good relationship, especially because he speaks French.
“So we are trying to have that relationship, not only on the pitch but even outside the pitch, to have that connection. He’s a good guy, he’s a humble guy. He works very hard in training.
“We try our best on the right-hand side but everyone is concerned. So we want to win as a team.”
Amad added: “It wasn’t easy at the beginning for him and for us. But the beginning was a start.
“Now we are trying to understand the system and we are trying to do the best every game. As a team we are learning every day with the manager because we believe in the system. But today we are really disappointed because as a team we demand a lot.
“We want to win every game because we want to bring this club to the level where they deserve to be.”
