Speaking to the Official Club Website, the West Ham midfielder said: "He knows his stuff and I'm sure he's going to be a great manager.
"I have been to a few games this season and obviously it's not gone as planned but he has brought in a number of players and it always takes time for players to gel.
"He may have his doubters but I'm not one of them. I'm definitely behind Jim. A lot has happened at the Club over the last year or so and I think the time to judge him is next year, not this one.
"The owner seems to be behind him and hopefully he will remain that way because I think Ipswich will reap the rewards over the next year or two."
Dyer currently sponsors the Ipswich Town Under 9's academy side and has been involved in several sponsorship deals for the Town academy over the last few years.
