Already some large scale housing developments started and planned for that area so as Bitzer says a discreet development like the training complex with relatively minor traffic movement hopefully shouldn't be an issue.
Objections have to be based on something tangible though not just 'I dont like it' so again, hopefully, there wont be any hiccups.
One thing that worries me in the clubs statement is the 'phased development' - probably being a doom and gloom merchant but will we get - dig a hole this year, dig another the next then maybe a fence or two after that and it'll take forever to finish
