The Red Devils have won six and drawn three of their last nine games in all competitions including a 1-0 victory over league leaders Arsenal last time out.
"We came off a couple of good results and sometimes you want the games to come thick and fast," Moyes told the press. "You can't do anything about the international break, whether you win or lose going into it.
"We're on a good run of form, we're feeling good at the moment, we have confidence about us and we want to try and keep that going.

United may field captain Nemanja Vidic when they travel to Wales. The Serbian was substituted with concussion during their 1-0 win over Arsenal but his manager says that he has recovered carefully.
"Concussion is something which you do need to rest [but] he's had his rest and we'll bring him back and hopefully he'll be fine," Moyes remarked. "It's not a serious injury.
"Concussion can be extremely serious but he had a week off afterwards and we've given him a chance to recover. We’ve picked him up slowly from there."
Red Devils star Michael Carrick sealed a new contract until at least 2015 on Friday – as exclusively revealed by Goal in October – and the Scot was effusive in praising his charge.
"He's recognised throughout the country as a great midfielder," Moyes enthused. "I'd be surprised if he's not in England's World Cup squad."
