The 25-year-old Dutchman, who has played a significant role in United's run of six consecutive wins, accepted rivals would have taken note of the 4-2 derby win over Manchester City on Sunday.
He insisted, however, that although United could win the title next year, they had to focus on securing a Champions League place - starting against Chelsea on Saturday.
Blind said: "I think Manchester United is always a club that is fighting for the title.
"Of course other teams are watching us, but we have to watch ourselves this season, our own games, focus on that and then we will see where it ends
"We don't have to watch for Chelsea
We have to watch for our own games, we have to look at ourselves
Every game is a final to the end and we have to believe in ourselves."
Blind credited a pre-match team talk from skipper Wayne Rooney about ending their run of four successive losses against City with giving the United players an extra edge on Sunday.
He added: "It was a thing that was always in our minds
It was going through the team
Everyone knew how important this game was, not only because it's a rat race in the last games, but also because of the history of the last four games.
"Wayne Rooney mentioned that in the dressing room before the game to all the players and it is something that you have in mind when you go on to the pitch
You saw how everyone was fighting for each other.
"Maybe after the first five minutes we were a bit like, 'What is happening here?' but after that we picked it up again and we did very well
And with the crowd behind us, it was amazing."
