Watford return home after a big win at Sheffield Wednesday last week but Sannino has warned that the players have much to do before the end of the season.
He said: "I would like my players to understand better that these last eight games are important to their futures. I think that in this kind of job, you are judged always by results. What's been done in the past doesn't count anymore, what is important is the future.
"I'm looking at the next eight games to assess the situation and it will be important for the future. The strength of the team is to be always demanding from themselves. They need to forget what they've done in the past and do their best for the next eight games."
Sannino, who followed Gianfranco Zola in the Vicarage Road hot seat, spoke about Clarets' boss Dyche, who was Zola's predecessor.
"I am not surprised by the job he has done because he is a good quality manager," Sannino said. "The surprise has been the minutes his players have played. There are eight or nine outfield players who always play, which is not easy.
"Burnley have shown everyone that it doesn't matter if you have a large squad because with 13 or 14 players Dyche has picked up 79 points. This could be a matter for reflection, to raise questions. Do we need a larger squad?"
He added: "When you miss players, you always have players who come in who are not tired and are fresh. So it won't make too much of a difference. Burnley are a compact and aggressive team where there is not just one player who is very good. Burnley's players are at the same level and they are a team. This is the main strength of Burnley."
Everyone has known all week of the problems facing us; Kieran Trippier and Danny Ings still on their way back from injury, Dean Marney suspended and now Sam Vokes and probably Junior Stanislas out of the reckoning.
Much has been said of how we might play in terms of formation but this has been played down by Dyche who said: "We all know the key stat and that's putting the ball in at one end and stopping it from going in at the other.
"Generally, though, our performance stats against Leicester were good. We just didn't penetrate as much as we hoped for and we didn't get bodies forward as high and as early as we normally do.
"That was the biggest change in comparison to the way that we've used Sam and the way he's played a big part for us. We like the two strikers to be up there and one coming off the shape, but it is what it is now and we know some good things about it. It is a different way of playing and it does take time to adapt to it.
"As regards to the players we've got, there's no natural out and out striker, but it sometimes comes down to yardages and I've made it clear many times. Whether you use 4-4-1-1 or 4-4-2, you're talking about 5-7 yards when one striker plays off the other.
"You can over think these things, although there are no massive differences. The 3-5-2 that Watford use is arguably the real different shape, but 4-1-4-1, 4-4-1-1 are very, very similar."
Looking at the players missing, he added: "We are probably stretched to our limits at the moment which is the most we have been as a squad this season, but it could all rapidly change in the next three to four days as the way the (injured) lads have come on this week has been very positive.
"We're in a nice position and there are big challenges coming our way, which continues with Watford on Saturday. We want to make sure that we'll go there in good spirit and with good understanding of the challenge that lies right in front of us, which we will do."
