Think to be healthy it has to benefit both clubs, and over an extended period of time. If Xia is serious, then it does mean he has some loose change to throw around and isn't skint like some have worried.
I read somewhere that Lyngby has a good reputation for scouting young players. If so, then we could help them find a home. In fact, Bodymoor could become a training centre for those players. In return, Lyngby could be a useful outlet for players developed here. With two clubs working together there ought to be a lot more flexibility. Some good players have come out of Denmark and we've had several of them; some more would be welcome. Laursen no 2 to work alongside Chester when Terry departs, for instance
And of course it doesn't just apply to young players. Senior players having struggles to get game time could, ahem, do a useful job in showcasing their experience at Lyngby; even the Danish pastry business might benefit.
It's not just players. If Lyngby should happen to need a new manager maybe a Laursen / Mellberg team would fit, and who knows what that would lead to...
