United are on a six-game winning run, following their shock loss at Burnley in the Premier League in August.
Fergie said: “We had a bad start, there’s no doubt about that, but the form of the team has been coming on well.
“Our best performance was at White Hart Lane. I’m happy with our form now. We have the squad and my only dilemma is who to play.
“Usually October sees us become more consistent and hopefully that will be the case again.
“The squad is a strong one and my only problem seems to be who to pick for each game.”
