Surely he has the constraint of losing his best players, time and time again? He's not been in position that long, and lost McGoldrick, but effectively blooded Wilson as replacement. But we've now lost Wilson too; plus Clarke, Moussa, Baker, Murphy and Christie. These aren't just players we lost; they're our best players by some considerable margin. Those six players are head and shoulders above anything we currently have. All would walk straight into the starting line up for the next game.
Waggott stated all the Wilson money would be reinvented, and we'd pay a fee should Pressley need it. Have we? Really? Why is Pressley saying he has no funds then?
To answer your question; 'what constraints do we have that are different to other clubs in our league?' - it's that. No other club has lost so many of its prime assets. If there is one, I'd like to see it listed. If there's not, there's your question answered my friend
