Symons insists the USA international's savvy makes him a better fit for Premier League Bournemouth than the Championship, after his £750k transfer to Dean Court last month.
The man sacked in November last year oversaw the midfielder's pathway from the youth ranks to the senior side - so he should know what he's talking about.
Dallas-born Hyndman played under Symons in the Whites U18 and U21 teams before making his senior debut in August 2014, with Symons assuming the hot seat just a month later.
Hyndman went on to make nine appearances that campaign, but failed to hold down a spot before the manager got the shove.
Despite Hyndman's limited game time during Symons's tenure, the latter insisted he had always rated the American.
Symons told the Bournemouth Daily Echo: "When I took over, Fulham were rock-bottom so it was a real scrap that season. Emerson wasn't really suited to Championship football and that scrap. That's not his game.
"He is an excellent footballer with a really good football brain and a great appreciation of time and space on the pitch. He is an excellent technician who sees angles and passes.
"I always thought he was more suited to Premier League football than the Championship because of the style of play.
"In my opinion, he will suit Eddie Howe and the Bournemouth style very well. I think people within the game appreciate what an intelligent and good footballer he is, so I'm not at all surprised to see him move to a Premier League club.
"If you could pick a team for him to go to, you would say Bournemouth would be the ideal one. I think it's a good move for him and I think he will be a good player for the club."
"He's not particularly physical but that will come. He will probably be a relatively late developer.
"His football brain has always been top class. He will only get better as he gets stronger and more used to the pace of the Premier League."
Capped twice by the United States, Hyndman signed a four-year deal at Cherries after rejecting the offer of a new contract at Fulham.
