Many Rovers fans took to Twitter to express their excitement of the signing of the 24-year-old full-back, with most viewing it as a fantastic piece of business.
So, with the announcement of the signing, how did Doncaster fans react?
“Halliday who? wahoooo what a signing!!!”
Judging by the reaction of many of the Doncaster Rovers fans on Twitter, it seems like the signing of Knoyle is one that the fans are truly excited by.
Doncaster finished 14th in League One last season and they will be hoping shrewd signings like Knoyle will help them sustain a better promotion fight as they look to return to the Championship for the first time since the 2013/2014 season.
Whether Knoyle will be able to help Rovers challenge for promotion to the second tier remains to be seen, but his arrival has certainly given these supporters plenty of hope ahead of the new campaign.
