"I am definitely keen to carry on for another year," Cueto, who has been with the Sharks for his entire professional career and is now in his 13th season of first-team rugby, told the Manchester Evening News.
"I always said I wouldn't play on simply for the sake of it: I would only do it if I felt I could play on at a level I was happy with and that I was still contributing to the team. At the minute, I would like to think that I'm doing that.
"So, I will be speaking to Dimes (Sale boss Steve Diamond), and ideally I will be able to stay here. If that doesn't work out I would have to have a look around, but hopefully we can get something sorted out for me to carry on at Sale."
Cueto has won a brace of Amlin Challenge Cup crowns and an English Premiership title with the Sharks and he is convinced the current squad have what it takes to push on and bring some silverware back to the North West in the near future.
Sale sit at the top of Pool 1 in this year's Amlin Challenge Cup with three wins from four and a bonus-point victory at home to Worcester Warriors the week after this could see them qualify for the quarter-finals if Biarritz return from Oyonnax empty handed.
Cueto admits that the fact the club is doing well right now after a nightmare first part of the season in 2012/13 has added to his own sense of enjoyment and determination to prolong his career, although he knows that neither he nor the squad as a whole can afford to take anything for granted with a big few weeks of action ahead.
"It feels a good place to be at the moment and that naturally comes with winning. It helps when the team are playing well and it's no coincidence that this time last year I had hardly scored a try," added Cueto.
"Now the boys are playing well, we all know what we're doing and we're going well and scoring tries. I've got six in the league so I'm really happy with that.
"Fitness also has a lot to do with how I'm playing. I have felt sharper than I have for a couple of years. Although I played a lot of rugby last year, I had a knee problem that wouldn't settle down so it made things difficult for me.
"As regards the club, we're in a decent position, but one loss and we could drop two places in the league as the middle pack is so tightly congested. I remember when I signed my last contract four years ago, we were fifth in the league and had started well in the Heineken Cup. By the time February came around we were ninth and out of Europe, so you can never rest on your laurels, you have to keep looking to improve."
