The Turf Moor outfit have managed to take just nine points from their opening 11 games.
It means they ended Tuesday’s matches fourth from bottom and just a point above the relegation zone.
However, four of their nine points have come in the last two games. That was via a 1-1 home draw with Everton and a morale-boosting 1-0 victory at Arsenal.
And those recent results along with players coming back from injury have persuaded Dyche that the current Burnley squad are good enough to kick on.
The Clarets boss said: “We can only hope that it’s improbable that the injuries carry on, and that would be a good start.
“I’ve always said that when everyone’s fit, regardless of not signing loads of players, we still believe in the squad and how it can compete.
“It’s the reality of a season’s work. We got promoted the first full season I was here and we had 17 recognised first-team players and only two centre-forwards until January, so it can be done.
Dyche continued: “Is it helpful to have a deeper squad? Yes it is, the physical demands are higher than six or seven years ago.
“We have been unfortunate with the amount of injuries and I would hope and suggest that statistically that is unlikely to continue all season. But you never know and we have to be ready for that if it does.
“So is it helpful if we can get some players in? Yes. Is it vital? Not always.
“I believe in these players, individually and collectively. And I think that is a powerful thing going into the second half of the season, regardless of whether we get players in or not.”
