Former Dean Court favourite Moss believes Cherries are in possession of League Two's top stopper after the club secured Jalal on a two-and-a-half year contract.
The highly-rated 26-year-old has been one of Eddie Howe's key men in this season's promotion push and his consistency was rewarded with a new deal.
And Moss thinks his student can enjoy a fruitful career well into his late 30s.
Rating him against other goalkeepers, there's no keeper in our division that I've seen that is as good as Jal, said Moss, who was forced into early retirement by injury in summer 2008.
Going back through my career apart from the top Premier League keepers who have got international experience there are not that many you'd put above Jal.
He's 26 and I felt at my best the year before I got injured. At 30, I felt really good about my game, so there was probably a chance I would have gone on to improve from that age.
If he keeps fit, strong and clear of injuries, there is no reason why he can't play for another 12 or 13 years. You can more than make up for the fact it is physically harder with experience.
This is the first time in his career he's been really settled at a club. He has signed a good contract, played a year of solid football and the more he plays, the better he'll get.
I think we can all look forward to seeing Jal go on and become a real force in goalkeeping, then the only problem will be keeping hold of him.
Moss added: He's had a great season up to now. I think that he's got to be in the running for our player of the season award because his level of consistency has been outstanding.
That was the thing I strived for that consistency so the manager can sit on the bench, knowing 99 times out of 100 what he will get from you.
He's a hard worker and is constantly nagging me to keep thinking up things for him to do to keep improving his game.
He's easy to work with and he's also, with the fitness coach Jon Dalzell, added a new dimension to his game by doing a lot of strength, fitness and core work. It all goes in to the melting pot to make him a good keeper.
