Spurs' top four challenge collapsed last season as they were hauled in by the Gunners.
But Holtby told the Daily Mail: "No we’re not scared. That’s the past. We are prepared.
"We have a lot of players who have seen that but we are prepared now and we have to just focus on our game. We don’t look at the table, just win our games and at the end we can watch and hope that we are in the top four.
"We can definitely do it. We had 12 unbeaten league games, we had a very good run. And now we’ve had three disappointing games."
