County fan in peace here. Jim Gannon hasn't worked with Curle, he was playing for Shelbourne in Ireland when Curle was at Mansfield.
The rumours have been doing the rounds here for weeks so I'm not surprised to see Matty's move confirmed. Great creative attacking midfielder with an eye for goal. Played his best stuff for us in a number 10 role behind a number 9 linking midfield and attack. Was a marked man for the last few months of the season meaning his goals dried up somewhat but that simply allowed space for others. I wish him a successful time with you all, he's earned the right to be move full time.
Thank you for the info and good luck to your team in the new season.
