A 3-1 victory over Sunderland on Saturday ensured that Manchester United will top the league at Christmas and while other clubs await the opening of the window, Ferguson is happy with the current options at his disposal.
United secured high profile deals for Patrice Evra and Nemanja Vidic in 2006 but the only prominent January arrival since has been goalkeeper Anders Lindegaard, who joined from Aalesund in 2011, as Ferguson has mainly avoided the winter sales.
When asked if there are areas of his squad he wants to strengthen when the window opens, Ferguson replied: "No. The January transfer market has never been the best market and that has proved itself over the years. You get very few big transfers - all the big transfers are done in the summer."
United's most important acquisition of the previous transfer window was Robin van Persie, and the striker has proved to be worth every penny of his reported £24 million transfer fee, scoring 15 goals in 21 games in all competitions.
When signing Van Persie from Arsenal, Ferguson said he hoped the Netherlands international would be a catalyst in the same way that Eric Cantona was when joining the club from Leeds in 1992 and going on to inspire Manchester United to four league titles.
It was said that Cantona's team-mates raised their standards following his arrival, and Ferguson believes the same is occurring with Van Persie. He said: "I think it is happening. The attacking aspect of our game has definitely improved."
In the full interview which you can see above, Ferguson goes on to discuss comparisons between his current collection of strikers and those that won the treble in 1999, as well as revealing how his socialist roots remain vital to him.
