I also think Mellor will stay and will probably sign a 3 year deal.
Our issue is we have hardly no other players OOC this time other than Matagi and Farrell. Bruno im led to believe has signed. So its hard to see how we are going to strengthen the squad next year.
The year after we have Murphy, Clough Ferguson, Walne, Frawley & Taai OOC of which probably Murphy, Clough, Ferguson & Taai may retire at that point.
Its extremely hard to see Fergie and Murph getting new deals beyond their current ones even if they dont retire. As too at this moment in time I think it would be poor to give Frawley and Matagi new deals beyond their current ones.
For next year id probably let Matagi go and resign Mellor. Id then try and promote Dom Young, Ross Whitemore and Jack Flynn to the first team. Next year try and progress further and reach the play offs and then the year after we can hopefully really strengthen.
