Van de Beek started for United in Wednesday's 5-0 win over RB Leipzig in the Champions League, and is looking for more opportunities going forward.
He said: "Players always want to play games. Training is also nice, but the games… this is why you're playing football.
"I think a lot of games [means] we can improve always and I am sure that we will win more if we stay in the focus.
"Arsenal have showed that they have really good players, and I mean we need to be focused. We won yesterday and everybody's happy and it's good for the confidence and everything, but now we must go on to that game.
"A lot of big games are coming up now. A lot of games. We need to stay in the focus and then I'm sure that we make more nice wins."
