Burton do have quite amazing facilities which is one reason they're able to attract good players on somewhat lower-than-expected wages.
Thats right, no doubt the best in the country. They train at our national sides training complex (St Georges Park) and they also have a medical centre that is highly credited by FIFA for the rehabilitation (not in a Nile Ranger sense) of injured players. It cost around £120 million to build I believe. I stayed at the Hilton hotel within the complex a few years ago. Lovely place to relax, I would highly recommend it for anyone planning an away day there in the future.
