The Red Devils are currently nine points clear at the top of the table with 13 games left to play this term.
United are also in contention for the FA Cup and the Champions League – and Ferguson admits his side are approaching a crucial point in the season.
“You hope that the players realise that the league is there for them [to win],” Ferguson told the Daily Star.
“It’s obviously a big challenge and we’ve got the FA Cup and the Champions League as well. It’s always an important time.
“The players have shown great appetite for it. They showed that against Tottenham in the way they fought like hell to get a [1-1 draw] and were unlucky it went against them at the end. But we’re definitely in the right shape.”
