Forrester was released by Rangers, before making a bizarre move to Iran.
The 27-year-old was released by Rangers earlier this week after Gerrard saw no future for the ex-Doncaster and Aston Villa man, releasing him from his contract despite an impressive AFC Wimbledon loan spell.
During the 2017-18 campaign, Forrester had a hand in 11 goals with the League One outfit, as they staved off the threat of relegation by finishing in 18th place in England's third tier.
He returned to Rangers but was forced to train with the reserve side and has now decided to move after his contract was terminated by Gerrard's side. Kiernan responded to the news of Forrester's transfer, telling him to "do your thing brother".
Forrester managed 44 appearances for the Gers in all competitions after first joining the Scottish outfit under Mark Warburton in January 2016. He scored eight goals created three, but now leaves with a year remaining on his original deal.
Now, he links up with a side that are managed by Wales legend and former Real Madrid manager John Toshack, while Forrester becomes the first Englishman to sign for an Iranian club since 2015, when Korede Aiyegbusi joined Meshki Pooshan.
